I added route as you suggested and it shows when i type the route command
Code:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface

default 192.168.1.1 0.0.0.0 UG 1 0 0 vlan2but when i run the curl command it still returns the VPN IP address. Something to do with the default gateway?

I found this script for tomato with openVPN .... i wonder if it will work in ASUS- merlin... i assume Wan UP corresponded to wan-start in /jffs/scripts i should be able to substitute tun11 with ppp5 for my case?
Code:
# This code goes in the WAN UP section of the Tomato GUI.
# This code based on the contributions from this thread:
# http://www.linksysinfo.org/index.php?threads/route-only-specific-ports-through-vpn-openvpn.37240/
#
# And from material in these articles:
# http://linux-ip.net/html/adv-multi-internet.html
# http://fedorasolved.org/Members/kanarip/iptables-howto
#
# This script configures "selective" VPN routing. Normally Tomato will route ALL traffic out
# the OpenVPN tunnel. These changes to iptables allow some outbound traffic to use the VPN, and some
# traffic to bypass the VPN and use the regular Internet instead.
#
# To list the current rules on the router, issue the command:
# iptables -t mangle -L PREROUTING
#
# Flush/reset all the rules to default by issuing the command:
# iptables -t mangle -F PREROUTING
#
#
# First it is necessary to disable Reverse Path Filtering on all
# current and future network interfaces:
#
for i in /proc/sys/net/ipv4/conf/*/rp_filter ; do
echo 0 > $i
done
#
# Delete and table 100 and flush any existing rules if they exist.
#
ip route flush table 100
ip route del default table 100
ip rule del fwmark 1 table 100
ip route flush cache
iptables -t mangle -F PREROUTING
#
# Copy all non-default and non-VPN related routes from the main table into table 100.
# Then configure table 100 to route all traffic out the WAN gateway and assign it mark "1"
#
# NOTE: Here I assume the OpenVPN tunnel is named "tun11".
#
#
ip route show table main | grep -Ev ^default | grep -Ev tun11 \
| while read ROUTE ; do
ip route add table 100 $ROUTE
done
ip route add default table 100 via $(nvram get wan_gateway)
ip rule add fwmark 1 table 100
ip route flush cache
#
# Define the routing policies for the traffic. The rules will be applied in the order that they
# are listed. In the end, packets with MARK set to "0" will pass through the VPN. If MARK is set
# to "1" it will bypass the VPN.
#
# EXAMPLES:
#
# All LAN traffic will bypass the VPN (Useful to put this rule first, so all traffic bypasses the VPN and you can configure exceptions afterwards)
# iptables -t mangle -A PREROUTING -i br0 -j MARK --set-mark 1
# Ports 80 and 443 will bypass the VPN
# iptables -t mangle -A PREROUTING -i br0 -p tcp -m multiport --dport 80,443 -j MARK --set-mark 1
# All traffic from a particular computer on the LAN will use the VPN
# iptables -t mangle -A PREROUTING -i br0 -m iprange --src-range 192.168.1.2 -j MARK --set-mark 0
# All traffic to a specific Internet IP address will use the VPN
# iptables -t mangle -A PREROUTING -i br0 -m iprange --dst-range 216.146.38.70 -j MARK --set-mark 0
# All UDP and ICMP traffic will bypass the VPN
# iptables -t mangle -A PREROUTING -i br0 -p udp -j MARK --set-mark 1
# iptables -t mangle -A PREROUTING -i br0 -p icmp -j MARK --set-mark 1
# By default all traffic bypasses the VPN
iptables -t mangle -A PREROUTING -i br0 -j MARK --set-mark 1
# Spotify explicitly uses the VPN
iptables -t mangle -A PREROUTING -i br0 -m iprange --dst-range 78.31.8.1-78.31.15.254 -j MARK --set-mark 0
iptables -t mangle -A PREROUTING -i br0 -m iprange --dst-range 193.182.8.1-193.182.15.254 -j MARK --set-mark 0tomsk

Hmmm....reading up a little on reverse path filtering it seems like something you would not particularly want to turn off. I confirmed its turned on currently
will this part of the script make the router vulnerable to attack? i assume the routing won't work without it/
Code:
cat /proc/sys/net/ipv4/conf/default/rp_filterwill this part of the script make the router vulnerable to attack? i assume the routing won't work without it/
Code:
for i in /proc/sys/net/ipv4/conf/*/rp_filter ; do
echo 0 > $iI wonder why that is not working. I tried again....
Without pptp vpn

"94.232.XXX.XX"
curl -s --interface vlan2 http://ipv4.myip.dk/api/info/IPv4Address
"95.16X.XX.XXX"
I observed that the IP was actually changing when I used curl without "--interface". Using the interface, and it is now consistent, albeit quite slow for some reason.
Anyways I'm really not familiar with routing and using Iptables, so I think we need help from others...

There's some interesting information here: http://www.snbforums.com/threads/guide-pptp-selective-routing-split-tunnel.15620/
Perhaps some of it might be of help.

Hi Steffe, thanks a lot for your script, it's exactly what I was looking for to check my external double natted IP on a regular basis.
I noticed a problem with the local addresses regex for the 192.168.x.x subnets, it wouldn't recognize my WAN address 192.168.1.253 as local
Jun 9 14:14:26 custom script: Running /jffs/scripts/ddns-start (args: 192.168.1.253)

Jun 9 14:14:27 ddns: Completed custom ddns update
Jun 9 14:14:27 admin: CustomUpdateDDNS: DDNS update complete
I replaced the regex with '(^127\.)|(^10\.)|(^172\.1[6-9]\.)|(^172\.2[0-9]\.)|(^172\.3[0-1]\.)|(^192\.168\.)' which is enough for my needs and now the IP is recognized as local.
But I still can't get the script to update my noip.com DNS record, this is what I'm getting in the logs:

Hello grifo,
First of all, which asus/merlin version du you run?
I briefly tested the IP 192.168.1.253, and that works nicely. It is matched by:
if [[ -n "$(echo "$ASUSIP" | grep -E '^(10\.|100\.(6[4-9]|7[0-9]|8[0-9]|9[0-9]|1[0-2][0-9])\.|172\.(1[6789]|2[0-9]|3[01])\.|192\.0\.0\.|192\.168|198\.1[89])')" ]]; then --> https://github.com/Meliox/Utils/blob/master/ddns-start/ddns-start#L74
See: http://regexr.com/3g52m
Please check, and report back.
Furthermore, I am wondering why the watchdog is started after the custom ddns script is started.
If possible, please try and execute the script manual through Putty "sh -x ddns-start" > debug.log and upload the debug.log to for instance pastebin. Remember to remove personal details. Thank you

Hi Steffe,
Thanks a lot for your reply, which helped me fix the problem.
I'm running the latest version 380.66_4 on an RT-AC87U.
Firstly, I've reinstated your original regex and now it's working so I can only assume it didn't paste in correctly when I created the script with nano, although I did check the script line by line when it wasn't working and it looked good.
The other issue was that after making several tries and changes with your and other ddns-start scripts I had left my username as the my no-ip.com registration email address, which works when the update URL is pasted into a browser but not with the script. Below is what I was getting, manually running the script and after a reboot of the ISP router:
I changed that to my no-ip.com username only and it works great.

Hello,
Thank you for a great script, but I got some glitches.
My config: my WAN is private IP and second connection is l2tp.
In order to make it work I had to make these changes
So these changes work, they update IP record on no-ip.com but without them I have these in syslog
And it is doesn't matter whethere my external IP equals to the record on noip.com or not.
Thank you for a great script, but I got some glitches.

Code:
if [[ "$NEWIP" == "$(nvram get EXTERNALIP)" ]]; then
# ip has not changed there's no need to hammer the ddns provider, so compare it to the previosuly found ip and save in ram
# LogMe "CustomUpdateDDNS: (nochange) External IP address is current: $NEWIP"
# LogMe "CustomUpdateDDNS: Update not needed"
# /sbin/ddns_custom_updated 1
UpdateIp
else
UpdateIp

Steffe, thank you for the prompt answer.
Now I removed the strings of the script to original state and now I have the desired behaviour.
So I suppose, when no-ip.com have EX.TER.NAL.IP, script sees it and do not try to update it.
But initially at first start and furhter (without forcing UpdateIP) it set the address to the private IP of the WAN and didn't change it to the EX.TER.NAL.IP.
Or I have another version..
At first I used email as a login in script before even setting the username in no-ip.com.
After some tries and changes of the script I made a username and put it to the script.
Anyway, thanks for your job.
