Hello,

it could just be that the line between your remote site and your main site is saturated...what happens if you let the clients select the 'Basic' option on their login screen ? Can you check if the client's mailboxes are very large, or create a new client and have that client try to access OWA from the remote site ?

Thanks The router models are as follow ios 12.3 1700 ios 12.1 1700 pix 515 6.3

i can browse the print server website, but even owa seems to stall. May be i should remove my traffic shapping, just for the day.

Hello,

weid indeed...if the number of hops depends on the size of the packet, that must mean that somehow the intermediate devices route traffic based on packet size. Can you post the MTR results with both packet sizes, if possible ? I am interested in the intermediate hops...by the way, which country are you in ?

with packet of 1492 i get

with packet of 1000 i get

The columns are lost% sent and received. I wish i could do the test with a host inside the 10.10.11.x subnet but there are no hosts online today. The results look similar but the last row is 10.10.11.47 instead. I tried changing the MTU on the interface inside and on the clients but that did not work, i think i set it up too low to 576, I am thinking may be i can change the mtu on the mailserver or just increase it to

I havent test this but someone just mention to put this in the router's internal iterface ip tcp adjust-mss 1380

changing the mss did not work, i had to change mtu and mss it seems like that does the trick.
