Hello, I'm almost new on DDWRT so the issue could be not a very issue.
But I've searched in forum and I've not find any solution.
I'm running a R7800 with build 34320M.
I use Privatevpn service that is a vpn service.
So I configured DD-WRT router as OpenVPN client.
Privatevpn give a true private IP address on internet so the router connects using tunnel to this IP address that is used only by the single customer.
Now the issue.
With VPN connected, if I do a port test on the leased VPN IP address I see a lot of ports closed, and also opened ports like 80, 23 and 53. For gui, telnet and dns.
I've tried to connect from a different address on internet and I can log to router gui pointing to external VPN ip.
Obviously all this is not acceptable so, I've disabled Openvpn client.
I attach some screenshots.
I think that can be some missing setting in firewall, but I don't know where.

I also use PIA for VPN service.
My private network is protected by the PIA OpenVPN service through policy based routing. When I run Gibson's Shields UP!! connected to my private network I fail with open and closed ports.
When I connect through my guest network (not protected by OpenVPN) and run Shields UP!! I pass with perfect Stealth mode.
My router settings are the same for both tests.
I'm hoping what is being tested through the OpenVPN connection is the provider and not me. I'm hoping I'm protected by my router behind the OpenVPN service.
I just don't have enough expertise to know for sure. _________________ R7800 r53339 std (08/01/23)
Private network on bridge br0 = eth1 (vlan 1) + wlan0 + wlan1.
Guest network on bridge br1 = eth1.4 (vlan 4) + VAPs (wlan0.1 + wlan1.1) for IOT devices
(Roku's, Amazon Echos, smart switches, etc.) and guest.
Noob still finding my way.
swconfig dev switch0 set enable_vlan 1
swconfig dev switch0 vlan 1 set ports "1 2 6"
swconfig dev switch0 vlan 4 set ports "3 4 6t"
swconfig dev switch0 set apply
vconfig add eth1 4
brctl addif br1 eth1.4
ifconfig eth1.4 up
