[Gllug] proxy-arp and a vpn

Hello again

I am using a linux box to link a home network (well, a Thinkpad) to a
wireless ADSL router next door. 

Using NAT I had all sorts of problems, so I switched to proxy-arp, and
now everything works :)

For example, connecting to a VPN from behind NAT was beyond me. With
proxy-arp, the Thinkpad connects to the VPN easily, but the VPN doesn't
seem to work very well. 

On the other hand, if I use the linux router as the VPN client and NAT,
the Thinkpad can use the VPN without any difficulty. Which seems pretty
crazy to me.

any comments very welcome
Have a good weekend,
Tom Weissmann
