Hello everyone!
This being extremely disganting to understand the working of the virtual server for opening ports for the model Archer c20 see. 4.0 <W>. I got in touch with the support of my country and the same went to the most advanced support because neither they know how to proceed.
I need to open ports for access to devices via the internet and I'm not successful!
My scenery:
DHCP Range: 192.168.1.100 to 192.168.1.199

All devices are with fixed ip, out of range of dhcp, the devices are with ip in the range 192.168.1.1 to 192.168.1.20.

I opened the ports on the virtual server but it did not work.

Contacting my parent's support I was informed that I would have to reserve the ips on the dhcp for door opener to work. Ai I said, book as if the ip range is out of dhcp and the devices have ip fixed and are not assigned by dhcp. The attendant spoke good question, did not know to respond and spoke that had to send an email to the support 2 level.

Even then I went on the ip reservation and made the reservation for the ips out of the dhcp ip range and it still did not work.

Can anyone help to properly configure the virtual server of this router?

Missing my TP-link 841 wr, it works well on it!
