Ability to set non OpenSOHO device IP address as VLAN gateway.

[bomkz]

My current ISP disallows custom gateways, so I have my OpenWrt setup controlli g DHCP and DNS while my ISP router does the gateway/NAT job. however, since i can't control it via OpenSOHO.

Trying to add a gateway IP on VLAN brings up a device selection menu, and trying to create a new record does not let me add a custom IPv4 to my custom device.

Please try setting gateway to your DHCP+DNS router.

Since OpenSOHO does not set up the routing for the VLANs (That's something to do in Luci on that same DHCP+DNS router. This approach should be fine. The gateway field only configures which device will get the address entered in the CIDR. But otherwise it has no other functionality. So you can perfectly have your DHCP give an IP to your ISP router and then point your default gateway DHCP option to that ISP device.

If you get it to work, you can always make a PR for the docs https://github.com/rubenbe/opensoho/blob/main/doc/vlan.md . (or simply let me know, that would also be appreciated)
