Accessing the firewall's web UI from VPN IP net

[ram0042]

Hello:

I'm able to access all of my clients OPNsense firewalls using the VPN IP and obviously their LAN IP once I'm connected with a "Road-Warrior" setup.

Back at my office, I believe I have the same setup but I'm not able to use the VPN network IP of my OPNsense box "10.0.0.1" to access the web UI. I can use the LAN IP and it loads just fine. I port scan my client's 10.0.0.1 and port 80 and 443 are open. On my box they don't show up indicating that they are closed, although 22 and 53 show open (which makes sense to me) and I can ping no problem.

I tried to look at a live log to see if I'm being blocked but there's no entry.

I've compared my clients OPNsense box to mine and see no remarkable differences but what else can I check?

It seems like I removed other interfaces from the access for hardening purposes. "SYSTEM>SETTINGS>ADMINISTRATION>WEB GUI>LISTEN INTERFACES"
