Secondary IP addresses on interface problem

Howto add secondary IP address on interface? — Zyxel Community

There is no primary so I have
/ vrf "main" interface ethernet "ge4" ipv4 address "192.168.255.235/26"
/ vrf "main" interface ethernet "ge4" ipv4 address "192.168.255.253/26"
/ vrf "main" interface ethernet "ge4" ipv4 address "192.168.255.248/26"

With a VPN for interface Ge4 to nailed up to 192.168.255.243 my USG40 only that end is expecting from 192.168.255.235 which I think was the primary only the FLEX200H randomly picks how it sends VPN connection out from and so the VPN fails not much I can do so I had the other end nailed up to 192.168.255.235 to make it work for now.

So there need to be a primary.

Hi @PeterUK,

From your screenshot, the My Address part is still using the interface rather than fixing the virtual interface IP address. Please reference the below.

Hi @PeterUK,

Since the virtual interface cannot set orders now, could you help to change the VPN setting > Network > My address from the interface to a fixed IP address? This should avoid randomly picking the IP address.

It is fixed

The problem is when nailed up on FLEX200H side the source IP of ge4 LAN can pick from

/ vrf "main" interface ethernet "ge4" ipv4 address "192.168.255.235/26"

/ vrf "main" interface ethernet "ge4" ipv4 address "192.168.255.253/26"

/ vrf "main" interface ethernet "ge4" ipv4 address "192.168.255.248/26"

The other end is expecting say 192.168.255.235 but the FLEX200H uses 192.168.255.248 as source when nailedup and so their is a mismatch.
