I don't know if I'm in the correct forum. Please pardon me if I'm not.
We recently changed ISP's. They setup PPPoE which we were not running before. Now some of our software loads very slowly. QuickBooks in particular. Just after the ISP change we also loaded VPN client software (Shrew) on a couple of desktops (Windows XP Pro SP3). That is running super slow too. While troubleshooting that I noticed fragmented packets our MTU is 1464. I tried to edit the windows registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Ndiswan\Parameters
and that didn't help.
Our ISP's Tech told me to change the SonicWall TZ170 MTU setting (now 1500) to 1480, but I get an error:
Error: The MTU must be a value between 68-1500 in increments of 8 (e.g., 1492).
I'm not sure what to do or where to go to find an answer.
Thanks.
