Hi Everybody!

 

"Enable Application Optimized Routing" is not working if i have 2 WANs binded in "Policy Routing" for some local IPs.

Example:

WAN1 & WAN2 included into "Enable Bandwidth Based Balance Routing on port(s):" WAN1, WAN2

"Enable Application Optimized Routing" feature is ON

That does mean:

  • 4. With Application Optimized Routing enabled, packets with the same source IP and destination IP (or destination port) will no longer be distributed in the load balance

BUT! If to make a rule like this:

HOME ALL HOME_IPs IPGROUP_ANY WAN1,WAN2 Any Priority      

 

"Enable Application Optimized Routing" WILL NOT WORKING! (for the group HOME_IPs)

 

Also Policy Routing has another bug interfering with Load Ballance.

Some rules from this 2 great features are conflicting..

BUG2:

 

If I have WAN1,WAN2,WAN3. WAN3 IS NOT INCLUDED INTO Load Balance! WAN3 - is only for some special IPs routing. And if I will made this Policy Route:

HOME ALL HOME2_IPs IPGROUP_ANY WAN3 Any Priority  

 

This route will caused some another LAN IPs (not included into HOME2_IPs group) to be routing to WAN3....

Hi  @avpopov1977 

 

Thanks for posting here.

 

To understand the situation, please give us the following info:

1. How many WAN ports do you configure in total? What's their Internet service provider?

2. "Enable Application Optimized Routing" WILL NOT WORKING! (for the group HOME_IPs)

>>>How did you verify this? Please share your verification process with us, better with screenshots.

 

3. This route will caused some another LAN IPs (not included into HOME2_IPs group) to be routing to WAN3....

>>>Please share with us the related config screenshots;

How did you verify this? Please share your verification process with us, better with screenshots.

 

4. What's the firmware version of your router? When did you first notice these issue?

Hello @Vincent-TP 

 

1. 3WANs. from different providers. 2 x WANs (WAN1, WAN2) in Load Ballancing and one (WAN3) for Private LAN IPs group. 

2. Connecting from my ER8411 to remote web-interface ER6120. IP is changing in few seconds and i have to login again.

Here the log from 6120:

ID Time Module Level Content
1 2025-12-26 19:47:48 Remote Management NOTICE IP address x.x.223.143 succeeded to access the server.
2 2025-12-26 19:47:42 Remote Management NOTICE IP address x.x.120.7 succeeded to access the server.
3 2025-12-26 19:47:24 Remote Management NOTICE IP address x.x.223.143 succeeded to access the server.
4 2025-12-26 19:47:13 Remote Management NOTICE IP address x.x.120.7 succeeded to access the server.
5 2025-12-26 19:46:57 Remote Management NOTICE IP address x.x.120.7 succeeded to access the server.
6 2025-12-26 19:46:49 Remote Management NOTICE IP address x.x.223.143 succeeded to access the server.
7 2025-12-26 19:46:26 Remote Management NOTICE IP address x.x.223.143 succeeded to access the server.
8 2025-12-26 19:45:58 Remote Management NOTICE IP address x.x.120.7 succeeded to access the server.
9 2025-12-26 19:45:52 Remote Management NOTICE IP address x.x.120.7 succeeded to access the server.

 

3. BUG2 is very hard to catch.. And it caused only for few IPs from LAN.. Some time the system can working correctly, but later some of my users got an issues that all their traffic is going through wrong and not setupped for them WAN3-port.. The problem will gone after rebooting ER841 for few hours... I making the "Crunches" by adding the rule into policy routing for every LAN IPs users binding them to WAN1,WAN2 (not WAN3) - it helps. But it caused a problem with Application Optimized Routing will not working.

 

4. Version 1.3.6 but this is an old bugs - they are in all previous firmwares... (( Load Balancing algorithm conflicting with Policy Routing if I have 3WANs and two of them in Load Balancing... ((
