I have 3.2 installed with setting DNAT and packet filter for both webadmin and ssh. This has been working fine and I can administer the firewall from anywhere. I am using DHCP on the external nic.
But since about 2 days now, I can no longer connect from external but can still get out and my dynamic IP has not changed. I have not made any changes whatsoever.
However, I oberserved that I can connect if the external system is on the same subnet as the dynamic IP of the external nic of the firewall. What I did was using a laptop which is not behind the firewall but also obtain dynamic IP from my ISP, and I was able to access the firewall.
What could my ISP been doing that is causing my not able to connect from others.
