I won't feel bad if you flame me with a RTFM, but does anyone know off hand which ports one would have to open on a firewall sitting in front of a Hub MX to let Meraki ClientVPN traffic (L2TP/IPSEC) through to said Hub?
UDP 500, UDP 4500, ESP 50, AH 51...? anything else, or not one of these?
Solved! Go to Solution.
UDP 500 and 4500
🤣😂 no worries @rafaelertel . Enjoy, it’s an excellent read
Today I had the same issue.
Port Forwarding UDP 500 and UDP 4500 to the inside LAN-adres of the hub will do.
Advise: test your Client VPN with a iPad or iPhone. This worked for me, immediately.
With the Apple clients you will see UDP 500 and UDP 4500 is okay.
MS Windows has problems with NAT-T (NAT Traversal) for ages.
