VPN on Private IP

[Alain Ganuchaud]

Hi,     I need an advice about the following design and the technology to use.   Please, find below, the topology of the network I intend to set up:                                   Provider/Internet   Remote Lan<----->FireWall<--------------->FireWall<---->Local Lan   Private IP                |              |              Private IP                                     |              |                                   V            V                               Static IP Adresses         FireWalls will be configured both with:   - RedHat6 (2.2.5)   - IPchains   - ipmasqadm with ipportfw for accessing internal web sites on both sides.     Now, I'm wondering about VPN.   Do you know if a VPN solution exists that can support such design?   I think the main difficulty is about Private IP vs Public IP.     If this is not supported, could you recommend another configuration?     Many Thanks for your help.   Best regards     Alain Ganuchaud   [EMAIL PROTECTED]
