Ignoring the reasons why but I need to configure a 3300 behind a 2820.
I need the following:
2820:
LAN1: 172.20.2.0/24
VPN: 172.20.2.0/24 + 172.20.1.0/24 to 172.20.3.0/24
Static Route: LAN: 172.20.1.0/24 to 172.20.2.252
3300:
WAN2: Eth 172.20.1.252 to 172.20.2.252
LAN: 172.20.1.0/24
The following is routing correctly:
1. All internet traffic
2. 172.20.2.0/24 to 172.20.3.0/24
3. 172.20.3.0/24 to 172.20.2.0/24
4. 172.20.1.0/24 to 172.20.2.0/24
5. 172.20.1.0/24 to 172.20.3.0/24
no routing
6. 172.20.2.0/24 to 172.20.1.0/24
7. 172.20.3.0/24 to 172.20.1.0/24
ie traffic to the 172.20.3.0/24 subnet is going to 3300 external WAN ip 172.20.2.252 but not routing inbound onto the 172.20.1.0/24 subnet.
Any suggestions as to what I should be checking?
Thanks
