[FW-1] Secureclient from behind SOHO-Router?



Hi,

the first time contact of a NG-AI SecureClient from behind
a SOHO router (i.e. NATting DSL router with dynamically assigned
IP Address) fails. It takes some time and the error message is
"Communication with gateway ... at site ... failed.

A tcpdump shows some traffic between SecureClient and the
port 264 of the firewall, then TCP to port 500, and then ISAKMP
(UDP to port 500). There's some traffic and then the error message is
issued.

I guess NAT is causing the problem and Visitor mode would be the
solution. But how to start this mode before doing the initial topology
download?
