Red Hat Bugzilla – Bug 23477
pump uses wrong addresses for sending DHCP requests
Last modified: 2007-04-18 12:30:33 EDT
My situation is the following: I have a home LAN, and internet access
through a cable modem. I have 192.168.1.x addresses on the LAN, and my
cable ISP gives me 1 public address through DHCP. That's where pump comes
in the pic...
I use a RedHat 6.2 box for doing NAT, where eth0 is the LAN side, and eth1
the cable modem side.
At boot time, first eth0 is configured with a private address. Then eth1 is
configured, but pump uses the private address from eth0 instead of
0.0.0.0... The result is that I get no response from the DHCP server...
When I disable eth0 at boot time, everything is working fine, I get an IP
address and so on.
Only eth1 will be configured now and no address is defined (yet)) at eth0.
Pump uses 0.0.0.0 in this case, and it works fine.
btw, I've been troubleshooting this one with tcpdump, and it took a while
before I figured what went wrong...
To be clear: the DHCP DISCOVER going out on eth1 uses 255.255.255.255 as
destination address, and the address configured at eth0 (192.168.x.x) as source
address, seen with tcpdump.
clearly seems like a duplicate of 23052. Any comments, Erik?
Yep. This is indeed a duplicate of 23052.
