18.7 Legacy Series / Cannot access resources on WAN interface

« on: November 15, 2018, 02:23:38 pm »

Hi,

I have installed OPNSense inside a virtual environment for testing. I have attached 2 network cards:
- WAN: 10.60.12.10
- LAN: 10.60.11.10

I have disabled the "block private networks" on the WAN interface.

I can:
- Ping or SSH to stuff on the 10.60.11.0/24 network
- Ping stuff on the 10.60.12.0/24 network
- Access stuff on 10.20.30.0/24 (or any other remote) network if routed via 10.60.11.1

I cannot:
- SSH stuff on the 10.60.12.0/24 network
- Access stuff on 10.20.30.0/24 (or any other remote) network if routed via 10.60.12.1

When I run tcpdump on the receiving end I can see incoming packets from the OPNSense machine. When I check tcpdump on OPNSense I see nothing.

Any ideas on how to proceed? Other VMs work fine so it is probably some configuration in OPNSense that needs tweaking.
