I need to tunnel one SSL VPN (F5, running on one debian host) through
another (OpenVPN, running on another debian host), but lose networking
(e.g., `ping`) after the F5 VPN connects. I'm not sure whether this
is due to my firewall/iptables or VPN configuration, but suspect the
former. Unfortunately I am not knowledgeable regarding networking, so
I'd appreciate any assistance you could provide.

First thing to check would be the routing table while the VPN is active.
The `route -n` for while the OpenVPN connection is active is here[3], which is part of a longer section[4] with "all the gory details" ...
and thanks! your prompt assistance is appreciated, Tom Roche<Tom_Roche@pobox.com>
