SGE2000P- How to block DHCP at port

[lightmind]

Hello,

I have a class C private network shared at two locations. The remote location is connected to the local network at the SGE2000p switch on port 1.

I am trying to avoid creating multiple vlans. Everything works great except DHCP.

I have a DHCP server at both locations, as well as an Internet connection at both locations. The DHCP servers have different gateways.

The problem is that when a client asks for a DHCP address it could get an address from the server on the remote network.

I want to be able to block the DHCP at the switch port (port 1) that connects the two parts of the network together. If possible, that would solve my issues.

Thanks!

I installed the latest firmware (had the old firmware, lacking many features).

Then I enabled DHCP snooping and added a trusted port from the Local DHCP server. That blocked the DHCP traffic from the DHCP server on the remote side. So half of the problem is solved.

However devices on the remote side still get DHCP replies from the local DHCP server.
