Loading probs with websites - MTU issue

[modnet25]

hi all,

if you have lags when loading sites or when some sites never load in the webbrowser and you have a DESKTOP FIREWALL installed then this might be a solution:

here is what i did to solve the probs: just open the regedit program (do this by pressing START - COMMAND - regedit).
then search the value HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters\Interfaces\[adapterid]

adapter id is a very long unreadable string like this --> {DEA96A6F-43A6-479C-9F04-6B9DAXX699F}
there should be several of these entries. choose the one which is showing your network settings at the right window pane. you can identify the 'right entry' by looking at the value DhcpIPAddress which hast to correspond with your own ip (check this by clicking START - COMMAND - cmd - ipconfig)
all other entries just show 0.0.0.0 as ip or the value does not exist - only one shows your ip correctly.
found

then add a DWORD-Value, name it MTU and assign the value hex 5d4 (that's 1492 in dec).

reboot and test again.
for me it worked out probably.

the firewalls affected by that are:
kerio in any version
outpost (only tested the last release downloadable at augnitum)
