Hello,

 

I have two remote sites.
I connected the 2 sites with an IPSEC tunnel

 

Communication is ok between vlan 1 (10.31.6.X) of site 1 and vlan ( 10.64.23.x) 1 of site 2.

 

However, I cannot communicate between vlan 2 (10.174.1.x) of site 1 and vlan 1 ( 10.64.23.x) of site 2

I configured the ipsec tunnel on the 2 routers

 

Router site 2

 

 

Router site 1

In the ipsec SA, I find that the second link, is not ok on the 2 routers

 

 

I don't see where the error could come from, have you ever had the case?

 

I've been pulling my hair out for 2 weeks '(

If I'm not wrong, in standalone it's impossible.

 

You will need the Omada controller, to add multi-nets to the Ipsec rule.

I have an omada controller at each site, but I find them quite unstable, so I don't associate the routers.

I managed to configure it in standalone, it's slightly more complicated than with the omada
