Having issues making 2 VLANS work on same 1238 switch.

This should be very simple but it isn't working for me.

I am trying to get 2 VLANs setup on a 1238 17.08.02.00

VLAN1 is data and VLAN 2 is for voice.

DHCP is provided to both VLANs by the switch.

Connected to a Watch Guard

Port 1 is VLAN 1 on both the switch and WG

Port 2 is VLAN 2 on Both the Switch and WG

The switch sees the Yeahlink phones via LLDP and I see they are in deed assigned to VLAN 2 (via MAC forwarding table).

I have assigned static settings to each phone and everything works fine.

When I set the phones for DHCP, they never get DHCP though, (Everything on VLAN1 does)

When I enable the VLAN2 interface and assign an IP address, The phones then grab DHCP, however the Adtran becomes unreachable, I lose internet connectivity on my LAN, and can't pull an IP address on Computer.

Re: Having issues making 2 VLANS work on same 1238 switch.

I don't think this will work.  The old version (G1) of the 1238 doesn't support routing or IPs on more than one VLAN interface.  I don't think it can service a DHCP scope on a subnet for which it doesn't have an IP.  Certainly a renewal couldn't take place because that requires a unicast to the DHCP server's IP, which it doesn't have for VLAN 2.  Why don't you allow the Watchguard provide DHCP.  A switch isn't a great device for that - limited DHCP features.
