Checksum errors from IIS & VPN

Hi,

I'm trying to access an Intranet IIS server via a Checkpoint VPN. When I look at the packets between IIS and VPN I see...

1. A small (60 - 66 bytes) packet from client to VPN to IIS
and just after this
2. A 1440 byte packet from IIS to VPN to client with both an IP checksum error and a TCP checksum error.

I'm new to analyzing packets so I don't exactly know what this means. Is the IIS server telling the VPN the packet it sent had a bad checksum or is it vice versa?

Thanks for any ideas.

Fred
