Hi guys,


R4 (EZ remote) -----R6(EZ SERVER) ------ (EZ vpn client)

The crypto map on R6 is applied to both interfaces (the one facing R4 and the 
one facing test pc)  Both EzVPN clients are able to connect, however I noticed 
one interesting thing.

The peer address on the clients must be the ip address of the facing interface 
otherwise the returning traffic from the server to the client will black holed 
by the server. The received  packets are decrypted by the server but the 
returning traffic won't be encrypted.

RIB/FIB are OK, they are pointing to the right interface/next-hop.

Does anybody have an explanation why is this happening?

Thanks!
Oszkar
