Error display in VPN site to site

[filiberto.aguirre]

I have set site-to-site VPN using a 2801 and 870 router.

I get the following error

: IPSEC(crypto_ipsec_process_proposal): peer address XXX.149.101.183 not found

what could it be the problem?

I attach the config of both sites

1.I am assuming that you already have Phase 1 policy defined on both side, if not please configure it.

2.Your ACLs should exactly be opposite to each other which are not.

3.Try removing crypto map on Site2 and re add it as it is showing "Incomplete!"

4. Use the same rules as used for crypto map (here ACL 115)to exempt them from NAT
