I've been fighting this for a bit, and don't seem to be making headway.
I have an old laptop I am making into a LEAF Bering firewall. It's currently connected to an external serial modem, and a PCMCIA NIC (3com). There's no DMZ, and just the two interfaces (ppp0, eth0).
I've proven that the PPP part works, but I've been having trouble getting the DHCP server to work on the internal network address on eth0.
I've worked through the installation instructions (many, many times). I've Googled and checked the FAQs.
I've gotten some assistance with the problem here before, and implemented those instructions (ref traffic from Erich Titl, suggesting a delay script in /etc/init.d --thank you, Erich).
Now, DHCPD does not seem to recognize eth0 and I cannot ping the firewall from itself, using ping 192.168.1.254 (the address assigned to the firewall on eth0).
This can't be a Shorewall problem since Shorewall NEVER restricts traffic from the firewall to itself.
******************** The messages at boot read:
Starting dhcpd on eth0:
No subnet declaration for eth0(0.0.0.0)
This isn't a Shorewall problem either -- it is your dhcpd configuration. DHCPD thinks that it should be handling eth0 and you haven't defined a subnet for that interface (as the message says).
As amazing as it seems, not all problems are Shorewall configuration related...
