Site-to-site with CGNAT
Posted: Wed Aug 03, 2022 8:15 pm
Hoping someone can help me with newby questions. I had a Ubiquity Unifi VPN link between 2 home sites; both with dynamic public ipv4 addresses. Recently, I changed out one end (my current site) to StarLink (CGNAT). The Unifi products cannot negociate the CGNAT end with their current software. I am trying to configure SoftEther to recover the VPN connection, hopefully using the NAT traversal function on the StarLink end. StarLink doesn't allow port forwarding or IPv4/IPv6 assignments. Teamviewer is being used to make adjustments to the distant from me. The 2 sites (windows 10/11) have separate subnets (192.168.222.0, 192.168.1.0) so I added a layer 3 switch; switches on each end are "running." I installed stand alone servers on both ends. There is activity with the virtual hubs on each side; see attached file. The various devices on each end were populated into the hub's routing table. Both sides have unique DDNS Hostnames. Ping times out when I try to ping the opposing sites; the IPs from within the opposing local LANS, the opposing DDNS Host names, or the unique IP range assigned by SoftEther (in the range 192.168.30.0). On the two Unifi firewalls, I have opened up unique port 5566 (on both ends)to incoming packets.
Questions: how are the unique LAN addresses assigned by SoftEther (in the 192.168.30.0) used? Do I need to enter the DDNS Hostname somewhere specific on the computers opposite one another to get the 2 sites to see each other? Do I need to set up a cascading variable to connect the 2 sites? As I am not an expert in these areas (I'm a newby), I am hoping someone out there can help me with what I am hoping to be a simple solution so I can again map drives on the opposing computers.
Thanks!
