The router says it is VPN passthrough. How about reboot the router? After you can log into the router, i think you can try to turn off the Hardware NAT to check the UDP can pass through or not.

I suspected that it would be the same problem as using IPSec for Cisco VPN client. Try to disable the hardware NAT and see if it work. Certainly, this is a damn bug of TP-LINK firmware and you may send the support log to them but I don't know if they can really solve it.

If you would give up the hardware NAT, forget this fxxking firmware. Use DDWRT and I think you would be happier.

I read that its a problem with the Atheros chip they use. Should always check the chip inside before we buy :/
