for your clients connected to ports 1/3 & 1/4. where on those 2 subnets is your IP helper?
Oh just noticed that this is your question... are the cliients not connected to a switch that could have the helper address?
are you also saying that pxe failed on the same lan? If devices are within the same broadcast domain as the image server you do not need a helper...
I have never tried this but just trying to work out why it would fail.
Hi @MickBall - thank you for taking the time to reply!
Under Network > DHCP > DHCP Server each ethernet interface has its own DHCP configuration. (I couldn't figure out if there was a better way to get DHCP working on all ports with the same IP range.)
ethernet 1/2 > 192.168.1.0/26
IP Pool: 192.168.1.20-62
Broadcast: 10.199.155.63
Subnet Mask: 255.255.255.192 (255.255.255.192/26)
ethernet 1/3 > 192.168.1.64/26
IP Pool: 192.168.1.65-126
Broadcast: 10.199.155.127
Subnet Mask: 255.255.255.192 (255.255.255.192/26)
ethernet 1/4 > 192.168.1.128/26
IP Pool: 192.168.1.129-190
Broadcast: 10.199.155.191
Subnet Mask: 255.255.255.192 (255.255.255.192/26)
Yesterday I made progress on this by doing the following
Deleted a vlan that showed up in Network > VLANs.
Deleted the DHCP relay I created that referenced this VLAN
Deleted a NAT rule to translate incoming TFTP connections to the PXE server (I had forgotten I set this.)
After committing the changes, PXE works only for devices plugged into the same interface as the PXE server (so ethernet 1/2). Unfortunately PXE does not work on interfaces 1/3 or 1/4.
For what it's worth, I don't need/want to have this specific setup: I don't need/want a DHCP server and different IP range/pool on each interface. I would much prefer a single 1 DHCP service that serves up IP's from a single IP range/pool across all three interfaces (ethernet 1/2, ethernet 1/3 & ethernet 1/4) so that PXE works across all three. The team that manages these devices does not seem to know how to do this so their solution is to plug in a switch in interface ethernet 1/2 and plug everything (PXE server, clients etc.) in there. This is not ideal but it will allow me to do what I need.
Hi, I am just wondering if you have found any resolution about this issue. I have a very similar situation here. We have a PAN 820 in the office. The DHCP is configured on firewall. I have defined a server network in this case which has the routing sub-interface on 820. I also defined PXE option 66 and 67, plus a policy based forwarded on TFTP service to the server IP if the request is hitting on the gateway from the same network range.
Are the clients and PXE server in different zones? If so, you'll need to have security policies allowing the traffic from client to server.
Have you taken any captures on the interfaces to see what the traffic is doing?
