USG 100 Flex - How to change VPN Port?

EricM

Hi,

On my USG, I have 3 VPN in service. Is it possible to change port for one VPN? (500,4500 → 54500,54600 for example).

Thanks,

No its not possible to change IKE ports Unless you add more hardware at both ends not 100% sure Zyxel can do it but it be like this.

Zyxel USG > port 500 > another NAT router change port 500 to 54500 > internet > another NAT router change 54500 to 500 > Zyxel USG sees 500
