Cisco pix udp packet size edns (bind8/9)

[Stephane T.]

Hi,

Just a quick update on this problem : cisco has just released version 
6.3.2 which allows you to modify the DNS/UDP max packet size :

fixup protocol dns maximum-length <size>

this seems to solve the EDNS problem that a lot of people had.

Now, what would be a decent value for max packet size ? We had problems 
mainly with Akamai'd web servers (like Yahoo!).

I think that :
no sysopt nodnsalias inbound
no sysopt nodnsalias outbound
are new options too.
