v1.5.6-beta7 Release: ***Disclaimer: This is a beta release and has been untested***

Manually upgrade to this beta by running the following command" ***Allow for cronjob to relaunch the script***
Code: 
/usr/sbin/curl -s "https://raw.githubusercontent.com/Ranger802004/asusmerlin/main/wan-failover_v1.5.6-beta7.sh" -o "/jffs/scripts/wan-failover.sh" && chmod 755 /jffs/scripts/wan-failover.sh && sh /jffs/scripts/wan-failover.sh restart

To revert back to Production Release:
Code: 
/jffs/scripts/wan-failover.sh update

Beta Readme

***HIGHLIGHT*** Script will now create an alias as "wan-failover", once script is updated and restarted. Consoles can now use the new alias instead of the full script path "/jffs/scripts/wan-failover.sh". Consoles open while the script is updated may need to be restarted or the following command executed.
Code: 
source /jffs/configs/profile.add

Release Notes:
v1.5.6-beta7
- General optimization
- Added a confirmation prompt to Restart Mode.
- Fixed visual bugs when running Restart Mode.
- Load Balance Monitor now triggers Service Restart function during failover events.
- YazFi trigger during service restart will no longer run process in the background to prevent issues with script execution of YazFi.
- IP Rules should no longer create conflict with other scripts such as VPNMON.
- Target IPs for both interfaces can now be the same the Target IP.
- Added Recursive Ping Check feature. If packet loss is not 0% during a check, the Target IP Addresses will be checked again based on the number of iterations specified by this setting before determing a failure or packet loss. RECURSIVEPINGCHECK (Value is in # of iterations). Default: 1
- Resolved issues that prevented 4G USB Devices from properly working in Failover Mode.
- Moved WAN0_QOS_OVERHEAD, WAN1_QOS_OVERHEAD, WAN0_QOS_ATM, WAN1_QOS_ATM, BOOTDELAYTIMER, PACKETLOSSLOGGING and WANDISABLEDSLEEPTIMER to Optional Configuration and no longer are required to be set during Config or Installation. They will be given Default values that can be modified in the Configuration file.
- Created new Optional Configured Option to specify the ping packet size. PACKETSIZE specifes the packet size in Bytes, Default: 56 Bytes.
- Resolve issue where script would loop from WAN Status to Load Balance Monitor when an interface was disabled.
- Load Balance Mode will now dynamically update resolv.conf (DNS) for Disconnected WAN Interfaces.
- Fixed Cron Job deletion during Uninstallation.
- Corrected issue with Failure Detected log not logging if a device was unplugged or powered off from the Router while in Failover Mode.
- Modified Restart Mode logic to better detect PIDs of running instances of the script.
- Created Alias for script as wan-failover to shorten length of commands used in console.
- Fixed issue where if the USB Device is unplugged and plugged back in, script will now leave Disabled State to go back to WAN Status.

Published a minor update to v1.5.6-beta7 regarding USB Device Status. Just reinstall using the install command above if you have already installed.
 
Can someone please tell me a command, to see which version of this script I'm running?
 
Run the update command

Ah yes, using the beta releases requires the special command string I provide however it's not officially built into the update stream for the script. At that point, when the script launches, it logs which version it is running and you can use that. Change the install at the end to restart if you already have the script installed with a config file. Install would be used for a fresh install of the script. I have already thought about simplifying this in a later release.

See example below:
Code: 
Aug  1 12:22:49 wan-failover.sh: System Check - Version: v1.5.6-beta7
 
For version V1.5.6_beta7, this is still the case:

So my Iface for ISP01 is eth0, and for ISP02 is eth4, and when ISP01 is Primary WAN(Connected), and ISP02 is Secondary WAN (Hot-Standby), you can ping 8.8.8.8 via eth0, but NOT eth4.

After using

Code: 
//jffs/scripts/wan-failover.sh switchwan

ISP01 is Primary WAN(Hot-Standby), and ISP02 is Secondary WAN(Connected), you can ping 8.8.8.8 via eth4, but NOT eth0.

Code: 
ip rule list | grep -e "8.8.8.8"
produces
100:    from all to 8.8.8.8 iif lo oif eth0 lookup wan0

Code: 
ip route show default table 100
produces
default via X.X.X.X dev eth0

Where X.X.X.X is my Primary WAN(Hot-Standby) Gateway IP Address (these two lines were blank in beta6)

I haven't tried my tests of shutting the ISP01 WAN off like tests before hand (just using you "switchwan" command so far), but wanted to know if this helps in determining why failovers work, but failbacks do not, unless you shut off ISP02.

For some reason your WAN1 is missing the IP rule for it and possibly the IP Route for table 200.

EDIT: If you're having issues with Failback still, I need logs. So far in most cases that doesn't seem to a problem so I have to see what issue is going on with yours to determine what is going on.

Wait, I see what you have going on, that is definitely strange. The IP Rules / Routes look right so not being able to ping out of your WAN0 interface appears to be another issue going on. Do you have any firewall rules set up to block outgoing ICMP? Is there a bridge router in front of it that may be doing this? Is 8.8.8.8 routed to anything else like a VPN Tunnel?

Not as far as I know, I run basic OpenVPN server with OpenVPN clients to connect to it, nothing special

Just ran Failover Test and Failback test from ISP01 to ISP02 (Failover works), and then power up ISP01, and Failback fails.

When I run the "switchwan" command, ISP01 takes over again, and ISP02 goes back to being Secondary WAN(Hot-Standby).

If there are any commands you need me to run to test, let me know.


Failover and Failback used to work in V1.5.5 Final release, but I am not sure if your script used the same logic as these current beta releases.

Work with the beta8 release I just published, it probably doesn't have your issue resolved but I need you to collect debug logging for me to see what is going on. The failback loop should escape and return to WAN Status if the IP Rule or Routes are missing so if it is just staying there I need the logs to determine why.

Does this help as part of the debug logs from beta7 on Failback Failure?

I'm assuming you're deleting the Rule and Routes out of the Debug logging? It looks like everything is place just your router is unable to ping outside of WAN0 while it is down, is it still working if you go back to v1.5.5? As of right now v.1.5.6-beta8 should be better at handling coming out of the Failback loop. Are you able to manually ping from the router if you specify -I eth0? Are you using the default packet size?
Code: 
ping -I eth0 8.8.8.8

I am REDACTING the Debug logs for Privacy, and I am still unable to "ping -I eth0 8.8.8.8" when ISP01 is down, and ISP02 is up and primary.

I am also unable to "ping -I eth4 8.8.4.4" when ISP01 is up and is primary and ISP02 is in Hot-Standby.

I will have to test rolling back to V1.5.5 in a bit, as network is getting busy...

Check these when you are unable to ping and verify the Rules and Routes are in place, if they are there is something else at play here.
Code: 
ip rule show
ip route show table 100
ip route show table 200

This is the Failback Monitor Loop in v1.5.6-beta8, as you see if it is missing an IP Rule it will break the loop to return to WAN Status to recreate it, also if the route(s) IP(s), Gateway(s), don't match, it will also break the loop to go recreate them.

Do this for me, manually create these rules and see if it you are able to ping, if not continue to the next rules.
Code: 
ip rule add from all to 8.8.8.8 oif eth0 lookup wan0 priority 100
ip rule add from all to 8.8.4.4 oif eth4 lookup wan1 priority 100
Add these if you are unable to ping with the first rules.
Code: 
ip rule add from all iif lo to 8.8.8.8 lookup wan0 priority 100
ip rule add from all iif lo to 8.8.4.4 lookup wan1 priority 100

Also send me this please.
Code: 
ip -V

Do this for me, manually create these rules and see if it you are able to ping, if not continue to the next rules.
Code: 
ip rule add from all to 8.8.8.8 oif eth0 lookup wan0 priority 100
ip rule add from all to 8.8.4.4 oif eth4 lookup wan1 priority 100
