Help needed to work around a TCP NAT port binding timeout issue on the WAN network that our system uses. This is somewhat of a special case because the WAN is through satcoms. Specifically, clients on the GGSN tun0 connection may keep TCP sessions open but silent for >5 minutes, and the satcoms closes unused TCP ports after silence for 5 minutes. All we need is the GGSN to periodically generate a few additional TCP ACK messages for ports that have been silent for 2 minutes. We don't want to use the similar Linux global settings for tcp_keepalive_time because that impacts other TCP sockets. I have a lab system available with source code on a public IP address you can access. I expect this will take about 10-15 lines of code and around 2-3 hou...
