Title: Single Interface WAN Connectivity
Post by: dphonov2 on November 19, 2020, 12:14:09 AM

Hi All,

I have an ASA Firewall as the default gateway in an environment on 192.168.5.x.

I'm trying to deploy a single NIC OPNSense on 192.168.5.51. Seems easy enough. Bring up a VM, configure IP on the solo interface (IP 5.51, GW 5.1, DNS 5.2, just like all other hosts).

I can ping locally, I can resolve. But I can't browse traffic or ping from shell to the outside world.

I can see the ASA returning packets and delivering them to OPNSense, but its dropping them on the floor.

I have another use-case where I set this up with multiple NIC's and all is well so far.

Is 2 NICs a requirement?

Thanks in advance

Nevermind, I had a misconfiguration and I'm a terrible person for not checking.
