Here's a weird one:
I have an Actiontec T3200M gateway, on DSL, not fibre.
The Actiontec's WAN IP is 100.82.x.x.
When I go to Whatsmyip, it reports 209.121.x.x
I have my own router connected through the Actiontec via Bridge Mode. Same thing.
TP-Link WAN IP is 100.82.y.y.
Whysmyip reports it as 209.121.y.y.
No wonder why all my attempts at port forwarding never work, even though the TP-Link was fine when I had a Speedtouch modem. Wasted hours on this the past few months!
Has anyone seen this before? Thanks.
