VWAN DHCP Issue

Product Discussion Peplink Balance
1

I have a balance 20x with VWAN enabled. WAN is connected to AT&T Fiber Bridge Mode IP 99.xxx.xxx.xxx and LAN 4 is configured as VLAN 299 Connected to a T-Mobile Home 5G Modem via DHCP IP 192.168.12.XXX. My LAN DHCP range is 192.168.0.0/24.

Every now and then as well as when the 20X is rebooted clients on the LAN side get a DHCP address from the T-Moble gateway (192.168.12.XXX) this causes multiple issues on my LAN. All LAN ports are set to access mode with only VLAN 1 access except for LAN4 on the 20X which is VLAN 299.

Why are devices getting DHCP addresses from the VWAN? How can I prevent this from happening?

I am also experiencing this issue with a balance 20x when I have a virtual WAN connection enabled. Have you had any luck resolving this issue and/or have you opened a support case for it yet?

No I have not. It’s still happening and it’s getting very annoying. Is your ipv6 enabled? Also, was it happening on older firmware for you? I’m on 8.4 and I believe it started after upgrading.
