Is there DHCP proxy under FreeBSD? I use ISCdhcpd beta_5_14 and I think
that it isn't DHCP proxy.

I am trying to forward UDP packets from microwave bridge. Management for
bridge runs on novell. Under cisco router I forward UDP packets with the
aid of 'ip forward-protocol udp 170'. My question is how I get this
function under FreeBSD? Now I know about natd (network address
translation). Do you know another solution?

(Next, I have other microwave bridge. This has ip, management runs on w95. 
But implementation of ip stack is strange (bridge certainly isn't able to
fragmentation) and I can't use management program behind router (cisco or
FreeBSD). So I also want to use natd.)
