Virtual private networks / Re: Forward ports to web over site-to-site

« on: January 11, 2023, 06:10:24 pm »

When I set up a portforward on the vps to point to an IP behind the local firewall, I can check the logs and see that the packets are reaching the destination. I confirmed this with UDP netcat. If I try going back the other way though, with TCP, it looks like the packets get lost between the destination and the local firewall. What should I do?

Virtual private networks / Forward ports to web over site-to-site

« on: January 09, 2023, 05:51:11 pm »

I am trying to set up my network so that I can access my network's local services from a public vps with a static IP.
Here is a diagram of what I'm trying to accomplish:

Code: [Select]

                                         
 x.x.x.x is the static ip of the vps
 z.z.z.z is the ip of whatever is running the local service i want accessible from outside

I was able to get the firewalls talking to each other over both wireguard and zerotier, but my portforwards don't work due to I think the way the (source?) nat is configured. How can I set this up? Thank you.
