Having the same issue, monitoring.

I thought of just changing my subnet mask but I suspect it’s far more involved than that.

I’ll Google around about ProxyDHCP, that sounds like the least convoluted solution - but I’m happy for the help if you have some tips, especially relevant to my configuration…I do appreciate that. I’ve been running CentOS 6 and am happy with it so far. I hope to not have to reinstall everything and start over, since Trinity Rescue Kit was a BEAR to get the config right (some late nights involved and I can’t remember exactly how I got it to finally work, but it does–except for the whole internet connection issue). But if I have to I have to.

Running a Fog server for PXE boot only, on a small network.

Two NICs on my server: eth0 is regular network traffic, eth1 is attached to a small switch where machines are connected to PXE boot … the reason for this is because the business network runs a Cisco router that is also a DHCP server, and my PXE server is also running dhcpd for IP assignment on the second NIC, and I want to avoid a conflict.

Can successfully boot from Dell Diag, Memtest, TRK, Parted Magic, etc… but can’t access internet (or network outside of my server.

Here is the output of my ifcfg-eth1:

[CODE]DEVICE=eth1

The 192.168.1.2 is a Windows server that runs our DNS.
I have iptables turned off so there is no firewall (not needed inside the network, we’re already nicely firewalled).
I have a feeling that the issue is somehow with the IP scheme but am not sure how to change it without broadcasting a second DHCP server across the network and screwing up all the other computers. I am extremely new to Fog and TFTP, and fairly new to Linux in general. Let me know if you need any other output that I have forgotten.
