Well I started here: http://sel.icann.org/node/715#fn1 and figured that it was a way to force the packet size and protocol so that I could fit it to known constraints in the PIX eg: Fix to 512 bytes and if the PIX is rejecting anything over 512 bytes there is a simple answer. Fix to 4096 bytes and it forces to EDNS (v0) - as can be seen in the output, to see if the PIX is just dropping all EDNS.. obviously the resulting size sent back I cannot control (except by limiting the maximum size), so the next step was to query all (or a selection) of the servers being traced through. What I can't figure out is why I can query the servers directly and get a response but the trace fails. Any insight will be greatly appreciated. Michelle
