Code:
root@LR-Remote:~/firewall.d # uname -a
FreeBSD LR-Remote 10.3-STABLE FreeBSD 10.3-STABLE #0 r300092: Wed May 18 01:03:38 UTC 2016 root@releng1.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC amd64
This machine is IP 1921.68.1.11, and all iNet traffic on port 22 is forwarded to it from the router... I am accessing it from 192.168.1.201 (a DHCP address) and when ever I turn on the firewall it locks me out. It's a headless system so I have taken to running a second terminal window with the following command to ensure the firewall turns off after 20 seconds just in case it doesn't work. But, for the life of me I cannot figure out what the problem is!
root@LR-Remote:~/firewall.d # sleep 20; pfctl -d
Any help would be greatly appreciated!
Here are the rules...
Code:
root@LR-Remote:~/firewall.d # cat /root/firewall.d/pf.conf
