Is COX blocking port 4500 (IKEv2)? It used to work but recently from my mobile phone (tried a T-Mobile and AT&T LTE connection) I can't reach port 4500 on my home router. I can get to port 500 (the other IKEv2 port) fine.
I don't see it on the list of blocked ports, but it would be odd if both Tmobile and AT&T blocked outgoing port 4500 since a lot of people use LTE for VPN, so I'm left with the conclusion that COX is blocking it.
Anyone have any ideas?
