I have a NETGEAR ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308. On WAN 1 i have a NETGEAR DGN2200 connected to adsl and on WAN 2 I have a sky provided THOMSON router.
The NETGEAR on WAN 1 is connected to BT, the THOMSON to sky.
The internet works fine but any port forwarding for incoming is blocked. I was going to dial in to the NETGEAR on WAN 1 and change the operating mode to modem only but can't get into it. The internal address for the PROSAFE is 192.168.0.2, the address for the DGN2200 192.168.6.1 and the address for the THOMSON is 192.168.5.1.
The external addresses for the PROSAFE are 192.168.5.3 on WAN 2 from the THOMSON and 192.168.6.3 from the DGN2200.
I can get into the THOMSON using the address 192.168.5.1 from any machine on the internal network but when i try 192.168.6.1 to get into the DGN2200 i only get page cannot be displayed.
