How do I properly route VPN traffic past two firewalls?
- Network setup: DSL Modem/Gateway/Router(FW1) >> Router(FW2) >> VPN Server
- Ports open on both routers/firewalls:
- L2TP (UDP 500, 1701, 4500)
- PPTP (TCP 1723)
FW1: 192.168.1.x FW2: 192.168.2.x (VPN server is on this network)
Am I missing support for other protocols through the firewall (non-port related)? If I DMZ FW2 from FW1, then user can connect. <-- Is this the only solution?
