Problems with VPN

Hi,

I have set up an L2TP VPN connection for my office. This is working flawlessly from all networks I've tried from except for my home network. The only reason I can think of is that the public IP of my home and office network are in the same subnet.

E.g.

Home network
Public
111.222.333.001
Internal
192.168.0.1-254

Office network
Public
111.222.333.002
Internal
10.10.10.1-254

I know that equal internal nets can cause problems but I have not heard about public IP interference like this.

Do you have any ideas?

This is not peer2peer and the configuration is working fine from other networks so I'm not sure what configurations you are refering to.

Having public IP addresses for home anf office in the same subnet is problem!
If IP addresses are really in the same subnet devices will try to ARP to resolve MAC address, but you need to route packets.
Having the IP addresses in the office and home in the same IP address range sounds impossible. :)

Thank you, I guess I'm out of luck then since my ISP won't assign me static IP or refresh DHCP.
