How to use SmartLink and a Flex-6600M connected to a PACE 5268AC gateway?

W4AFK Bruno

"CoPilot AI" says that a Flex-6600M cannot be setup for SmartLink when connected to a PACE 5268AC fiber gateway (1 Gbps U/D fiber here at home)

It says that I need to install a (low cost) router, then configure the Flex and the router to port forward 4993 and 4994, then tell the PACE to place that router in DMZ+

I'd like to hear back from anyone who has experience with this setup and fiber gateway.

Note that this radio will NOT remain in my home but will be used at a remote site to replace a 6400 being sent for repair. I confirgured the radio at home BUT encountered this problem after I registered SmartLink. Registration is confirmed but 4993 and 4994 are not forwarded, so no SmartLink (test comes back RED).

If push comes to shove, I can assume that all is OK for the remote site although I'd hate having to head up to the mountain site (5600 feet level) to find our it doesn't work. This being said, as the current 6400 works fine, my assumption is 99% certain (never say "100%" LOL) that this 6600M will also work. At the mountain site we do NOT use UPnP but manually forward for security reasons
