Packet flow explore for main route unknown

PeterUK

ZyXEL VPN300 V10.02(ABFC.1)

I have a backup 4G dongle and I get in main route this I think it might be happening when the 4G renews the IP and adds another unknown to the list, it does not seem to be causing any problems however.

Hi @PeterUK

From the screenshot, the cellular interface gateway is 192.168.3.1, and the VPN300 interface GE6 IP/subnet is 192.168.3.1/24 by default.  

It looks like it was caused by subnet confliction. Can you change interface GE6 IP and try it again?

PeterUK

GE6 was already changed to 192.168.252.1/255.255.254.0.

Hi @PeterUK ,

Which 4G dongle are you using ? Can you send me your configuration file via private message. I would like to do some test based on your configuration file.

Just wanted to update this as it was fixed with 10.02(ABFC.2)ITS-WK47-r90761 but the change to V4.35 the fix might have been lost as of testing with V4.35(ABFC.0)ITS-WK47-2020-01-02-1912000979D the unknowns are happening.
