Solved on Windows by forcing the MTU to 1492. This is a global setting for all interfaces.
Manually changing the MTU might lead to other problems. An how low to you want to the MTU? There might be tunnels, etc. involved which might lower the MTU even further.
Doing it the right way and having security allow the MTU exceeded? Not a hope in hades. Paranoia rules.
Only Idi^w clueless people drop ICMP completely. It breaks TCP. Yes you can fix around this problems but doing so will most probably cause other problems. I hope these people will also block ICMPv6 completely as well. This way they'll have no connectivity at thus will cause no problems for the rest of the world. <rant/> cheers Jens -- ------------------------------------------------------------------------- | Foelderichstr. 40 | 13595 Berlin, Germany | +49-151-18721264 | | http://www.quux.de | http://blog.quux.de | jabber: jenslink () guug de | ------------------------------------------------------------------------- ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe
