hello everyone

i try to setup a network-network connection using freeswan. there's a
netscreen firewall at the other end and my gateway is behind a
firewall doing nat. there's no port forwarding on my side, because
just my gateway is allowed to initiate the connection.

i experienced some really strange problems...
first i tried to connect directly from the workstations with the
appropriate roadwarrior config on the netscreen. it worked from a
notebook with the netscreen client, but not from two other
workstations that had the same os and client installed. then i decided
to try net-net from my linux firewall to the netscreen directly. when
i do tcpdump i can see that my gateway is sending packets to the
netscreen, but it gets no answer. in the remote box' log i can see the
connection attempt, but it's dropped because of failed
authentication...

does anybody have the same problems or knows what to do ?

thanx
