I have configured a VPN using OpenVPN with Tap interface. I am using a bridge for this configuration. I have IPv6 turned off. Likely irrelevant to this topic but it reduces potential red herrings. Everything appears to be working correctly HOWEVER, when I use the OPNSense DHCP service I get handed an IP within the range I am expecting HOWEVER cannot connect to my private network. When I use the OpenVPN DHCP service, then everything works fine. This is configured in Server Bridge DHCP Start / End.
Now, I compared the route table on the client between these two configuration and find that I have an additional (and incorrect, I believe) route entry when I try to use the OPNSense DHCP service. I cannot find where this route entry is coming from however I think this is the cause of the connectivity issue (please help me identify the solution!). I attached the table in a file. For this example, I connected from a hotspot as a source of remote connectivity.
I can provide more details (config files, etc. as necessary but didn't want to clutter this topic up unless necessary.
I am running the following:
Server:
OPNsense 23.7.1_3-amd64
FreeBSD 13.2-RELEASE-p2
OpenSSL 1.1.1v 1 Aug 2023
Client:
OpenVPN GUI v11.31.0.0 Windows Gui
OpenVPN v2.5.8 - I installed this version because 2.6.x appears to have compatibility issues with the above version of OPNsense
