Title: Questions Regadring Subnets
Post by: Julien on May 29, 2023, 05:56:13 PM
Hi Guys,

i hope someone can point me to the right direction here.
we have from ISP and /29 Subnet which we have configured our WAN on
XX.XX.XX.XX/29 WAN1
we have added the other 8 IP to virtual IPS and it works fine.
with the second  subnet /29 we did the same add it to the Virtual IPS.
and add both gateways to the System: Gateways: Single

this week we got the 3th subnet to test for our 10GB up links with the same subnet.
when i tried to add the 3rd gateway its error out

The following input errors were detected:

The gateway address "X.XXX.X.X does not lie within one of the chosen interface's IPv4 subnets.


is this because the WAN is /29 and not /32 ?

your help is appreciate it.

thank you

not sure what the intention here is. Are you trying to set up a 1:1 NAT or just use IP Alias or something else???

thank you for your answer.
i just been doing some reading and i think the issue is related to the 23.17_1 with the gateway switching ect..
i'll have to revers back to 23.1.6 but the box is not reversing.
i'll have to reinstall it
