workgroup bridge through wlapp net

omahrez — Sun, 04 Jul 2021 06:23:31 GMT

hello,

We are connecting a cisco router (819) to wireless lan network (lwapp) through its wireless interface.

clients ---> 819 ---->AP (WGB) ------ lwapp ----- AP ---> LAN ---> servers.

since the clients are on the same subnet as the the VLAN on the lwapp, everything works great.

When we add a new L3 VLAN on the 819 router, and we try to ping the clients from the servers, the packets can reach the clients but never received by the servers back. it seems like the bridge is dropping the packets when they go back from the client to the servers.

NB: when we use a GRE tunnel from the 819 to the LAN, everything works great.

any idea?

thank you.

heloma.

George,

is my scenario feasible without GRE tunnel ?

thank you.
