Hello Everyone, I posted this in the sysops only group but got no reply.
I thought maybe I was in the wrong group so I reposted here in hope I might get an answer.
I switched internet providers from Xfinity to Centurylink. Now I cannot get to the BBS from outside through another xfinity location. When I ping the local address I get a different address from the remote computer. When I first set this up it worked for about 3 days and now nothing. Anyone have any suggestions?

What do you mean by "ping the local address" and "get a different
address from the computer"?
Do you know your public IP address? Have you tried http://vert.synchro.net/scanmyports.ssjs to test your open ports?

I suppose you are having a double NAT configuration? Do you have 2
routers in your network? which OS are you using?
try this:
www.displaymyhostname.com
what do you see?
in a cmd prompt:
tracert www.google.com

I am at a remote location with an xfinity account. When I ping cpugod.synchro.net from this location I get the ip address of 75.169.169.147 which is not the address when I ping the bbs machine locally.
And that IP address seems to change.
I am at work now so I can't get into the BBS to get
that IP. However, The address seems to be the same after a few days. I will get that IP when I get home. I will try the open port tool you mentioned. Thanks Digital Man.

The best way to resolve a hostname to an IP address is to use the proper tool (e.g. "host" on Linux, "nslookup" on Windows). "ping" can work, but it's also going to try an ICMP echo request, so it's not really the right tool for the job.
When you say "ping the bbs machine locally", I'm not sure what you mean.
And that IP address seems to change.
If you're saying that the public IP address of your BBS computer (or gateway) changes, that is somewhat normal.

cpugod.synchro.net has this info in the synchro.net zone file:
75.169.169.147 ; 5adea85f Mon Apr 23 2018 08:45 pm
Which means it hasn't been updated since April-23. Make sure the 'dyndns' timed event is running on your BBS so that the hostname (cpugod.synchro.net) points to your current public IP address.

Hey DM, Hawkeye gave me the clue. The is an option on this modem called UPnP NAT-T: which was enabled. Once I disabled it traffic was free to
come in and Synchronet was able to do the DYNDNS. It's working now.
Thanks guys!
