Re: Switched to Comcast Business - problems

I don't know if this is the same setup as you have but I just had Comcast Biz installed at a company I support, the tech gave me this info

»10.1.10.1
login-- cusadmin
password-- highspeed

It lets you log into their modem. I haven't had a chance to look at it really at all so I can't say if this is a solution for you, but maybe this might help some?

That's the customer admin that let you setup port forwarding, changing the subnet range, etc. It doesn't let you put the gateway into bridge mode. There was an older SMC model that you could terminal into and set it to bridge mode, but Comcast wised up and wanted something that locked out the customer from doing it.

Connect JUST your router to the SMC, then everything else connects to your router. Then assign your router's IP address to the DMZ. It bypasses all firewall rules then.

That will bypass the SMC's firewall rules, but it will still be a cascaded NAT connection, and that can still be problematic for some applications.

This does not work tried it, then went to try it again on a different SMC that feature was not listed under that firmware version, all you can do is disable/enable the DMZ feature will all the SMC's with the new firmware, they want to sell external ip packages.
