Cisco 3750 and watchguard xtm530

Any advice needed.
i got a freshly configured cisco 3750 switch and will be creating a new vlan to add all our ip cameras (qty 40) that came in. Would it be better if the switch is configured as a dhcp server or does the watchguard need to be configured as the dhcp server.

It depends on if your 3750 was a layer 3 switch or not if this is possible.  You are probably better off configuring the Watchguard as the DHCP server if that is where all of your other DHCP pools reside.  If you have the cameras on a separate VLAN than the management interface for the switch, the switch may not be able to hand out DHCP to those clients.

Its a layer 3 switch. The reason i preferred doing it on the switch is not put additional load on the firebox. I managed to get it up the switch and client cameras are getting ip's from the switch, however no getting internet access when i tested with a laptop.

Maybe i need to create a trunk port from the switch to one of the optional ports on the firebox.

You would need to make sure the switch and the watchguard have the respective ports set up as a trunk, and the vlans are allowed in the trunk.

Also make sure the watchguard has an IP in the subnet/vlan that the cameras are on, and set the DHCP from the switch to push the default-router as the IP of the watchguard IP that is on the camera vlan.

You will need to make sure the watchguard is seeing the vlan you set up as an inside interface, so that it will perform NAT to the outside for your internal camera vlan users.

No Trunk port config needed.

you can have VLANs for internal networks.

then port on 3750 that connects to watchguard LAN port just assign that an IP on same subnet as watchguard LAN

e.g. watchguard LAN IP =
then on 3750
e.g. port 24 connected to watchguard
interface GigabitEthernet1/0/24
 no switchport
 ip address

then on 3750  have a default route ip route

and most important static route back from watchguard to send traffic from watchguard to cisco VLANs

e.g. if you have one VLAN with IP
then on watchguard create static route    Gateway = (cisco switch IP)

this should do the trick
i got similar setup running in my network.
