Hi, I configured dhcrelay on my shorewall router to send DHCP requests to a remote DHCP server. I need to listen for DHCP requests on on one interface (say lan.1). However, this interface has multiple IP addresses/netmasks. The remote DHCP server has only one scope and only one of the IP addresses of lan.1 is within that scope (say, 10.215.111.254/24). When sniffing traffic on the remote DHCP server, I see that the source IP address is one of lan.1's but out of scope (eg. 10.215.144.91). I managed to "fix that" with an SNAT rule, so now I see that the source IP address is the "right one", eg. 10.215.111.254. However, a wireshark dump shows me that within the DHCP protocol messages (DHCP Discover) the "relay agent IP address" is still out of scope (eg. 10.215.144.91).
I tried to search the dhcrelay man page to see if I could manually set this address. I don't believe there's any way SW can do this, right? This is more of a protocol issue, right?
