I'm setting up a gateway server on FreeBSD 5.3-RELEASE but I'm having problems getting FreeBSD to work with my ADSL modem (provided by ISP, no documentation, nothing on the net :-( ). The problem is I'm trying to get my private IP via "dhclient -v ed0" and all I observe is a series of "DHCPDISCOVER on ed0 to xxxxxx port 67 interval x" and in the end a message saying "No DHCPOFFER received". I've also used tcpdump to figure out what's going on with dhclient -- all I can see is the dhcp requests from my machine and *no* replies whatsoever. As if the ISP's DHCP server never received a request. The bpf device is included in the kernel config and I don't think it's a NIC problem (it works OK when I manually set the IP and ISP gateway). It's also not a network cable problem or ADSL modem problem (pls see below). Linux machines with dhcpcd and other Windows machines I've tried, all work OK and receive a private IP from my ISP. While monitoring the dhcp exchange with Ethereal, I can see 1 dhcp request and shortly after a dhcp reply with an assigned IP. Is there a problem with the particular version of dhclient in FreeBSD 5.3? Are there any solutions to this problem (preferably using FBSD-5.3)? --- Thanks in advance.
