I recently changed ISP. I used to have a modem, now I am using PPPoE. I had to add the PPPoE interface, and change Filter and NAT rules to use the new PPPoE interface instead of the WAN ethernet-1 gateway I was using before (I hope that is correct). Internet and everything seems to be working fine. GRC's Shields Up says my firewall is safe.
I have a NAS and a couple other services on my network. I also have DDNS setup and working. I have setup the appropriate port forwarding and everything seems to be working fine from outside my network. However, if I use the DDNS domain xxxxxxx.com:XXXX from within my network, it doesn't work.
Any ideas how I can make this work?
