Hi,
I have the fallowing picture:
Node1 --Internet--Node2---LAN using IP
Node1:
Win2K
VPN connection using PPTP
IP (public) = 129.197.23.232
Node2:
FreeBSD
VPN server (using MPD)
IP (public) = 129.197.244.6
IP (privet) = 10.77.5.2
LAN:
10.77.5/24
I set up a PPTP VPN connection between Node1 and Node2. Node1 gets privet IP
address 10.77.5.50. When I try to ping some computer on the LAN (not Node2)
with IP address 10.77.5.1 I know that computer gets the ping but does not
know how to get back to Node1. It might be a problem with the ARP because I
get an ARP error ([pptp1] no interface to proxy arp on for 10.77.5.50) when
I start MPD. I am not sure about this. And I don't know how to resolve this
problem.
I have no control of 10.77.5/24 computers (except Node2) but I want those
computers to see Node1 when it connects trough Node2. How can I make
10.77.5/24 computers to send packets to Node2 when they want to send it to
Node1? Thank you very much for your help. Best regards
Artem Tkachenko
