Netgear IPSec VPN passing through DSL modems?
Posted on 2009-02-24
I am trying to set up a VPN between two Netgear routers FVS318v3.
Router #1 is behind a managed Cable modem,
- modem wan 100.101.102.103, modem lan 10.1.10.1
- router wan 10.1.10.2, lan 192.168.15.1
Router #2 is behind a DSL modem,
- modem wan 126.96.36.199, modem lan 192.168.1.1.
- router wan 192.168.1.2, lan 192.168.22.1
Following FVS manual and other sources I tried to setup a VPN between the two. I tried opening / forwarding through the modems ports
UDP 500 for IKE
and UDP 1701
I must be missing some negotiation part, though - I am unable to establish conn.
Am I missing ports for IPSec VPNs? What else could cause the connection to fail?
