Cisco vpnclient, ssh-X11-forwarding and firewall

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I try to setup vpn connection. I use the Cisco vpnclient (4.8) on a FC5
system. The connection can be made and I make connection to a remote node with
ssh -Y remote.node. On the remote node I try to open some X-window (i.e.
xclock). If I have my firewall enabled the ssh session to the remote node
will hang for ever, if I disable the firewall the window is necely displayed.

Question : How do I have to configure my firewall in this case? (I use the
default  firewall comming with FC5). Which ports are to be inserted as
trusted?

If I use the vpnc from Extra's I do not have these firewall problems (I do
not understand at all why there is a difference)
However, the vpnc is not an option at the moment because it seems not to
survive the "rekeying" and I am always thrown out after exactly 7h36m31s.
