[SOLVED] vpn access to intranet blocked by Default deny rule

[bigfox]

[SOLVED]
After checking, it was a routing issue that prevented access to the server.
The problem is not related to firewall rules.
go to 'Additional BOOTP/DHCP Options', use DHCP pushing a static route to solve the problem.

-----------------------------------------------------------
opnsense ip :192.168.1.1
my other gateway ip :192.168.1.2
mywebserver ip:192.168.1.61  gateway :192.168.1.2 dns:192.168.1.2
my mobile use openvpn，ip :10.0.8.6
I use 10.0.8.6 browse 192.168.1.61

I want to use vpn to access my webserver and can ping, but access to port 80 is blocked by the default rules. Normal access without VPN
I tried setting up a few firewall rules, but nothing worked.

thanks

on 192.168.1.61 add static route to 10.0.8.0 through 192.168.1.1

Thank you
I added the route and the server is accessible.
But can I change the settings in opnsense to fix the problem?

No, it is a problem with your network design.

No, it is a problem with your network design.

Yes, it is indeed a network design issue and there is a problem with the routing that has nothing to do with the firewall. Thanks.

Well it is not a "problem" with the routing. It works as designed. Two gateways in one network will lead to this kind of problems. If the VPN gateway you are routing over is not the default gateway for the local machines they need static routes to find the way back.

You could work around with other types of VPN but if you're using VPN networks and tunnel networks you will face this kind of requirements.

Routing can easily become complicated with VPN and multiple routers.
