hi , i needed some port forwarding with socat or anything to connect my vps2 to my vps1 and load user and pass from it . i use vps1 and vps2 for openssh vpn so my users can get free internet without any filtering , someone helped me and i managed to port forward my ssh and load the user data on my vps1 with making this service file :
[Unit]
Description=SSH Forwarding Service
After=network.target
[Service]
User=nobody
ExecStart=/usr/bin/socat TCP-LISTEN:22,fork,reuseaddr TCP:vps1.example.com:22
[Install]
WantedBy=multi-user.target
but i also have v2ray panel on my vps1 with 2 config , one of em on port 443 with TLS on and cer , key file on my vps1 , the other on port 13081 without TLS . so i made 2 more file like this :
[Unit]
Description=SSH Forwarding Service
After=network.target
[Service]
User=nobody
ExecStart=/usr/bin/socat TCP-LISTEN:13081,fork,reuseaddr TCP:vps1.example.com:13081
[Install]
WantedBy=multi-user.target
both port 2255 and 13081 works fine but the port 443 that has TLS config doesnt work .
when i use this :
socat TCP-LISTEN:2255,fork TCP:sd1.aronashop.xyz:2255|socat TCP-LISTEN:443,fork TCP:sd1.aronashop.xyz:443|socat TCP-LISTEN:13081,fork TCP:sd1.aronashop.xyz:13081
all work fine even port 443 but the problem is when i close the SSH window it stops .
so how can i fix this port 443 problem ? i tried so many ways but none of em worked

Heya @driftinglightcyanurchin,
I just answered the question you provided here and in https://www.digitalocean.com/community/questions/how-to-forward-open-ssh-from-vps-to-vps?comment=196105. Sorry for the delay!
Anyway, I’ll post it here just to be sure:
To make the socat command run as a background process even after closing the SSH window, you can use the
nohupcommand combined with&. However, I recommend creating a systemd service for each port you want to forward, just like you did for port 22/etc/systemd/system/v2ray-443-forward.servicewith the following content:Do the same for the other ports (e.g., 13081) if you haven’t already created a systemd service for them.
Now, when you close your SSH window, the socat processes will continue to run in the background, managed by systemd.
