How to solve Local and Remote IP conflict?

  • I am trying to figure out how to solve a connection issue. I have to connect from our office to a customers office. Problem is that we are using the same ip address range on our subnets. They are both

    The customer needs to connect to a server on our network The setup is:

    CUSTOMER NET ->    CUSTOMER FW       -> Internet ->      OUR FW                 -> OUR SEVER      inside                       inside
                              outside                         outside

    I have tried making a tunnel to a local subnet called but the tunnel will not connect. Is it because of the bogus ip address, or is it someting else. I have tried adding the network under Firewall -> Virtual IP, but that did not help. I think I would need a virtual ip for the lan interface like, right? How do I do that?

    Would it be possible to then create a NAT rule translating a connection to an IP on the network to the server addres o our network And how do i do that?!?

  • You've got an interesting challenge there ;)

    The best solution is to change your network to something not in the 192.168.x.x range.  Maybe something in the 172.16-172.31 or 10. ranges.
