I hope you can help me
I've set up a VPN tunnel via a 2 Mbps SDSL link using a cisco 1811 at the remote end and a 2621xm at the central end (3DES SHA). At the remote end there are a number of Dell desktops and my HP Pavillion Laptop (also in the mix is a Cisco 2800 that acts as the default gateway before routing traffic to the 1811).
What is happening is via the VPN tunnel my HP Laptop can access everything with no problems however a number of the Dells are having connectivity problems for example my laptopcan access via http the opening page of a cirix metaframe server whilst a number of the Dells on display a quarter of the page, before it freezes.
Placing Ethereal onto one of the Dells and doing a capture. I see that there are incorrect checksums taking place from the Dell and retransmissions to the server(I disabled Checksum Offload on the Dell but it is still showing) My hunch that it is a MTU problem with the Dells./routers but I need further advice.
Can any body Help
