We have two 2811's at different sites connected via ADSL lines, the HO has fixed IP's, the remote office dynamically assigned IPs. Local LAN at the HO is 10.0.0.x, at at the remote 10.0.1.x. Could someone help by posting a config that would maintain a bi-directional tunnel permanently between the two sites? I'm assuming that the remote site must persistently initiate this tunnel, as it's the one with the dynamic IP address. IPSEC over GRE seems just fine, it's just that none of the Cisco published configs seem to solve our issue. br/
I have this problem too.
