Title: (resolved) routing docker IPVLAN L3. Traffic goes out, but the is no return.

Hi,

I am setting up some container in a docker IPVLAN L3, within a host.
I have added my host as a gateway for the subnet, in opnsense. (lesson learned)
I have added an explicit outbound NAT rule with source address my docker network subnet and translation target my WAN net

Ping will lose 100% of traffic.
All outgoing connections get stuck.

I can see all my outgoing traffic in green and matched against a rules in firewall. There is no blocked traffic.

Can you guys help me figure out what am I missing ?

Thanks.

JC

WAN address!

The source address in outbound Pakets need to be translated to the WAN IP.
