[Click] IPRewriter and ICMP packets

[Erik VandeKieft]

I noticed that ICMP packets that enter an IPRewriter element disappear and
don't make it out any of the outputs. What happens to them, are they
dropped on the floor? Why?

I know that there is a seperate ICMPRewriter class, but I that only seems
to rewrite the packet contents, not the actual IP headers. I need to
rewrite the source and destinations of ICMP packets, including pings, and
ICMPPingRewriter only allows you to do it for one static source and
destination, whereas I need it to be dynamic based on an IPRewriter's
table.

Do I need to implement this myself or can click already accomplish this?

Thanks,
