Multi Wan- switching GW

I have configured multi wan from this tutorial.
https://docs.opnsense.org/manual/how-tos/multiwan.html
Option failover

When wan1 is down I don't have internet on station (unless I turn on Firewall->Settings-Advanced->Allow default gateway switching) But this option is  deprecated.



My secenerio:
WAN - pppoe (default gw)
WAN2 - Static address

Routing Table (WAN pppoe UP)

ipv4 default 10.10.10.1 UGS 96 1492 pppoe0 wan
ipv4 10.3.4.0/29 link#9 U 107831 1500 em0_vlan100 WAN2
ipv4 10.3.4.3 link#9 UHS 0 16384 lo0
ipv4 10.10.10.1 link#14 UH 351 1492 pppoe0 wan
ipv4 10.10.10.5 link#14 UHS 0 16384 lo0

ipv4 172.25.101.0/26 link#11 U 24 1500 em0_vlan11 SRVALL_ZONE




Routing Table (WAN pppoe DOWN,WAN2 UP)

ipv4 10.3.4.0/29 link#9 U 107995 1500 em0_vlan100 WAN2
ipv4 10.3.4.3 link#9 UHS 0 16384 lo0

ipv4 172.25.101.0/26 link#11 U 24 1500 em0_vlan11 SRVALL_ZONE
ipv4 172.25.101.1 link#11 UHS 0 16384 lo0
ipv4 172.30.0.0/24 192.168.0.247 UGS 0 1500 em0 lan
ipv4 192.168.0.0/24 link#1 U 490384 1500 em0 lan
ipv4 192.168.0.1 link#1 UHS 11496 16384 lo0


Tables show routes when option Firewall-Settings-Advanced-Allow default gateway switching is disable.

Thank you for the advice



Hi,
I confirm the same behavior.
Lorenzo

Franco told me about a fix in 18.1.2 which could fix this possibly .. if not we'll try to find this one soon.

https://github.com/opnsense/core/issues/1821

18.1.2-2 -  still does not work

Next strange thing. I was add static route (Please correct me if I was this wrong). My steps:
1. Add Gateway (System - Gateway -> ALL -> Add ->  Serwer_OpenVPN )
2. Add Route (System -> Configuration -> Route
3. Add Firewall rule

When WAN ppoe is down and firewall option > Default gateway switching is enebled the routes looks:
ipv4 default 192.168.0.247 UGS 85 1500 em0 lan
ipv4 10.3.4.0/29 link#10 U 61557 1500 em0_vlan100 WAN2
ipv4 10.3.4.3 link#10 UHS 0 16384 lo0
ipv4 127.0.0.1 link#7 UH 49857 16384 lo0
ipv4 172.25.100.0/26 link#11 U 0 1500 em0_vlan10 MGM_ZONE
ipv4 172.25.100.1 link#11 UHS 0 16384 lo0
ipv4 172.25.101.0/26 link#12 U 69 1500 em0_vlan11 SRVALL_ZONE
ipv4 172.25.101.1 link#12 UHS 0 16384 lo0
ipv4 172.30.0.0/24 192.168.0.247 UGS 0 1500 em0 lan
ipv4 192.168.0.0/24 link#1 U 9290 1500 em0 lan


The default gateway set to Serwer_OpenVPN gate not to wan2. But on station internet goes through wan2 (Grupa_WAN).



Not sure if this is on GitHub already. If not, please record it there. It will surely get lost in the forum very soon.


Cheers,
Franco

Any update on this issue? I'm facing the same behavior. (18.7.10_3)


No, both WAN have static IP addresses

Then you should open a new thread .. multi wan works fine in general.
