Bill,
we have been looking at implementing OpenVPN to allow access to the
internal LAN. For a firewall, we basically have iptables with 2 nics doing
NAT. So would the OpenVPN server live inside of our private network and
just do some forwards with iptables on the firewall or would it be better
to implement it with by itself with 2 nics one on the public and one on
the private?
