Hi,
I need your help please because I'm not good with networking.
I have dd-wrt router with a public IP and I need to create a VPN with a friend that have the same my internet provider. I configured the VPN and opened the ports needed for it but I cannot ping his router and he cannot ping my router.
My public IP is released by DHCP:
IP: 109.xxx.xxx.108
Subnet: 255.255.255.128
my friend's IP:
IP: 109.xxx.xxx.60
Subnet: 255.255.255.128
How to configure the routers to route the requests? Or may be I can change the subnet masks to reach the hosts?

I was thinking about recommending WireGuard, but that is not available for your router let alone for your friends.
OpenVPN might work on those old builds but to make matters worse I do not think it is even available or working on newer builds.
Besides performance wise you will not get more than 2-3 Mb/s if you get it running at all.
What I do know is that those old builds have safety issues so it is not recommended to use those old routers/builds when the router is directly connected to the internet.
There is NO WAY to make serious progress w/ this problem given current conditions. The OP and friend are using seriously outdated hardware and firmware.
It's probably time for both of you to upgrade your routers to at least wireless AC (i.e., wifi5) with decent VPN performance. I use the ASUS RT-AC68U, and while it has less than stellar performance w/ OpenVPN (~30Mbps), I've seen as much as 111Mbps w/ WG (Wireguard).
Thanks for the suggestion, but the vpn run without problems from another location.
Router A did not see router B.
I go to place A and I ping to public ip router place B and it doesn't reply.
I go to place B and I ping to public ip router place A and it doesn't reply.
I go to place Y and then both routers reply to the ping.
