Cisco ASA to Openswan Error: no matching crypto map entry for remote proxy

Hybrid461 · ‎07-16-2010

I've been playing around with configs in both openswan and the ASA to try and get it working properly. I did have them talking with a dynamic crypto map set, but there would be issues after a powercycle on either device. Now im having trouble getting them to talk with static crypto maps. The full error is:

no matching crypto map entry for remote proxy 10.10.10.0/255.255.255.0/0/0 local proxy 192.168.1.0/255.255.255.0/0/0 on interface outside.

FINALLY figured it out. I changed the outbound_tunnel ACL to a number instead of a name. IMO that's a pretty dumb fix. So everything worked. But then i rebooted to test if it would work after reboot(which it didnt with a dynamic map). But i forgot to save my config changes. So i changed it to a numbered ACL. But i just get repeated: Received encrypted packet with no matching SA, dropping. Only other change ive tried from posted config is setting crypto map emap 10 set peer 200.200.200.2

Edit: Clearing out the SAs worked. Commands:

asa# clear crypto isakmp

asa# clear crypto ipsec sa
