This is probably more of a general PF question than Murus-specific, but this community is quite knowledgeable so here goes.
I'm trying to get port forwarding working with a VPN on El Capitan. The VPN client tells me that it has opened 220.127.116.11:56200.
When i use http://portchecker.co/check it understandably reports that the port is closed. To remedy this i created the following rule in Murus:
rdr pass utun0 inet proto tcp from any to any port 56200 -> 127.0.0.1 8080
The port is still closed, but when i create a python www server monitoring 0.0.0.0:8080 it is reported as open. So the port checker appears to detect that a process listening on the port.
The problem is that when i navigate to http://18.104.22.168:56200 the web server does not log a request or post a reply. I think perhaps i'm missing a PF rule to allow the www server to fully respond. Digging into it.. meanwhile any pointers would be appreciated.
