I am using Vyatta Remote Access VPN (PPTP) and NAT for proxy. When pc-A and pc-B are connected to VPN, pc-A ipaddress is 192.168.10.10 and pc-B is 192.168.10.11.
[pc-A:192.168.10.10]--internet(VPN)--[Vyatta]--internet(VPN)--[pc-B:192.168.10.11]
pc-A is visible from pc-B.(can ping each other.) But I don't want to connect pc-A and pc-B for security reason.How do I configure this? (firewall?)
