Which interface does "crypto map vpn" get assigned to?

[sander9214]

I'm setting up a site to site vpn and have been reading some examples, but my 871 uses a vlan so it confuses me a bit. Do I assign the statement crypto map vpn to the vlan1 interface or fe4 which is my WAN side.

If we knew more about your environment we might be able to give better answers. In general the crypto map is assigned to the outbound layer 3 interface. But I can not tell from your description whether fe4 or VLAN 1 is the outbound layer 3 interface. Does fe4 have an IP configured on it? If so then perhaps it is the outbound layer 3 interface and gets the crypto map. Or perhaps VLAN 1 is the outbound layer 3 interface and gets the crypto map.

If this helps you figure it out that is good. Otherwise perhaps you can provide some clarification of the environment.
