Hello guys. Anyone know how to clear/delete vpn profile from the router?
I don't mind doing it from ssh but don't know how to do that either.

Reason i want to do it cause router says there is routing conflict. I did clear route 192.168.1.1 but that works on cisco only i think as it did not do anything on asus.

If anyone also knows how to clear all routes in asus router as well that would be awesome. Thank you.
 
Client or server?

It's mostly in nvram. Assuming OpenVPN client 1:

Code: 
nvram show | grep vpn_client1

This will give you the list of vpn_client1_xxx variables. You have to unset all of them, one by one.

Code: 
nvram unset vpn_client1_rgw
nvram unset vpn_client1_dns
etc...
nvram commit

Yes, there's a lot of them...
 
Client sir. Is there also way to clear routes without breaking anything.
I'm assuming router will recreated routes automatically on it's own via profile.

My client is showing i'm having route conflict although i don't see any issue with browsing.

Thank you for help.

Routes are dynamically created when the client start, they aren't permanent.
 
Should i ignore that message that there is "route conflict" in asus right in vpn profile.
This is not in ssh but right in gui of vpn profile. I can post a screenshot if this is never seen before message.
 
I only run one client at the time but i do switch between 128 and 256 encryption and test like speed and etc. It's same vpn company, just different encryption profile.
I have same error but i never run them at same time.

But only when i imported 2nd ovpn config i got the routing error. It doesn't look like it's affecting anything but routing confilict maybe should not be igonored hence i'm asking. I'm attaching screenshot. Thank you for chiming in and merlin thanks for guidance.

OK, but in order to 'fix' my 'routing conflict' issues and have Selective Routing between two concurrent VPN Clients (from the same provider HMA) to two different locations

e.g.

VPN1=Hong Kong
VPN2=New York

I manually run this (crude hack) script FixRPDBVPN.sh after starting the second VPN Client

Code: 
#!/bin/sh
Issue_CMDQ(){
      /usr/bin/logger -s -t "($(basename $0))" $$ " " $@
      $@ 2> /dev/null > /dev/null
}
Issue_CMD(){
      /usr/bin/logger -s -t "($(basename $0))" $$ " " $@
      $@
}
/usr/bin/logger -s -t "($(basename $0))" $$ "RPDB multi-VPN Client Patching Started [$@]"

# Fix main - Probably easier to get user to specify route-nopull? but this prevents vpnrouting.sh from creating the RPDB rules :-(
Issue_CMDQ ip route delete 0.0.0.0/1
Issue_CMDQ ip route delete 128.0.0.0/1

PROCESS="0"
for LINE in `ip route show | grep "dev tun1" | awk ' {print "ip_route_add_default_via_"$9"_dev_"$3"_table_11"}'`
do

   /usr/bin/logger -s -t "($(basename $0))" $$ $LINE

   PROCESS="1"

   VPNID=`echo $LINE | awk ' FS="_"{print $8}'`;VPNID=${VPNID:4:1}
   MY_VPNTAB="11"$VPNID

   # Fix the current RPDB table 111,112 etc.
   Issue_CMD  ip route flush table $MY_VPNTAB
   #Issue_CMDQ ip route delete 0.0.0.0/1 table $MY_VPNTAB
   #Issue_CMDQ ip route delete 128.0.0.0/1 table $MY_VPNTAB


   # Add the only (default) route
   CMD=`echo $LINE$VPNID | sed 's/_/ /g'`
   /usr/bin/logger -s -t "($(basename $0))" $$ " " $CMD
   $CMD

done

ip route flush cache

#  Testing...
#   e.g. ip rule add from xxx.xxx.xxx.xxx lookup 111 prio 999
#        ...try to access http://geoip.hidemyass.com/ from xxx.xxx.xxx.xxx

#        ip rule del prio 999
#        ip rule add from xxx.xxx.xxx.xxx lookup 112 prio 999
#        ...try to access http://geoip.hidemyass.com/ from xxx.xxx.xxx.xxx
##       ip rule del prio 999


if [ "$PROCESS" == "1" ]; then
   /usr/bin/logger -s -t "($(basename $0))" $$ "RPDB multi-VPN Client Patching completed."
else
   /usr/bin/logger -s -t "($(basename $0))" $$ "RPDB multi-VPN Client Patching Skipped, no VPNs ACTIVE."

@RMerlin vpnrouting.sh creating the second VPN Client instance always seems to cause my Routing conflict.
 
Merlin i run simple configuration with no any type of scripts enabled. I just have two different profiles from same vpn company, one for 128 and one for 256.
I only run one at the time. I also wait 5 seconds before i turn on second one after i turn off first to give router a chance to complete the switch, just to make sure. Reconnect at wan is no for both for now during the testing.

My best guess since i don't do anything too fancy is that when second profile, whatever it is is imported it conflicts or at least it says so that it conflicts with routing stating routing conflict. Here is my log. I deleted my vpn company from profile for security purpose. The log pretty much looks like this in whole as every hour authentication re-valides itself as it's set to every hour. If this isn't enough i can reboot and paste again as i know then it shows more info.

Try this patched vpnrouting.sh

- copy the attached vpnrouting.sh.txt file to /tmp/vpnrouting.sh on the router
- issue the following command on the router
mount -o bind /tmp/vpnrouting.sh /usr/sbin/vpnrouting.sh

Hopefully this will help

I have been using the following VPN Client directive to quickly override the original vpnrouting.sh (for my tweaks) on a per VPN Client basis;)

Code: 
route-up   "/jffs/scripts/vpnrouting.sh"

rather than use this system-wide technique

Code: 
  mount -o bind /jffs/scripts/vpnrouting.sh /usr/sbin/vpnrouting.sh


OK, your patched version of vpnrouting.sh fixes the passing of args to openvpn-event!, and correctly flushes inappropriate table 254 entries for the first physical VPN Client to be started - usually VPN 1.

but sadly table 112 is still being populated with incorrect table 254 derived routes.

i.e. after starting VPN client 1

Code: 
admin@RT-AC68U:/tmp/home/root# ip route

xxx.xxx.xxx.1 dev vlan2  scope link
113.29.228.130 via xxx.xxx.220.1 dev vlan2

and after starting VPN client 2, both tables are 'corrupt'

Code:

P.S. I should probably now incorporate my FixRPDBVPN.sh code into openvpn-event now you are correctly passing valid args! :D

RMerlin,

Thank you for taking time to comment.

Clearly you have other priorities at this time, consequently investigating this insignificant issue shouldn't even be in your top 10,000 of things-to-worry-about!

@john9527 has kindly found time to investigate, and I'm sure you will agree, it is in capable hands.

Regards,

Did you remove your custom route-up directive? I just double checked, routing one client thru VPN 1 and another through VPN 2 and everthing is correct and working with the replacement vpnrouting (btw...that is the vpnrouting.sh from my fork).

Yes, ;)

NOTE: There is a warning when the route-up directive is detected..

but I'm 100% sure that your patched vpnrouting.sh was used in my (multiple) tests.

The duplicate rule entries for table main should probably be cleaned up at some point, but won't hurt anything. .100 thru VPN1 and .101 thru VPN2. (10.8.0.0 is my VPN server)

Here is my patched version of vpnrouting.sh (with eye-catcher to Syslog!!!) incorporating your patch to pass the appropriate args to openvpn-event.

For me, table 112 is now created correctly (and table 254 is correctly modified) when VPN client 2 is started after VPN Client 1:

I believe the non-fatal spurious

Error connecting - IP/Routing conflict

message is simply due to the fact that if either VPN is restarted manually via the GUI, then table 254 still retains the VPN end-point I/P addresses which do not get automatically removed.

i.e. if I manually remove the VPN endpoints

Code: 
ip route del 192.157.56.146
ip route del 113.29.228.130

...( or reboot!) before starting the associated VPN client then the I/P Routing conflict message never appears.

So I suspect that /etc/openvpn/client?/updown.sh should ultimately be modified to remove these routes?

Maybe this is still not working as maybe when i was getting rid of some info from client1 (which i no longer use) when i did apply maybe it was starting the client again hance stating routing conflict if two vpn clients are running at the same time. Although i can't visually see that is running. I'm only speculating here. I noticed that when i restart the router the routing conflict no longer is present, so maybe only when i apply changes which leads me to what i said. This is on 87u router.

FIXED: Applying changes to OpenVPN client page would start the client even if it was disabled/stopped.
