Hi there, Our firewall IP Tables on linux allows file transfers up to 1mb talking to a secure web site using sa fileup Files over 1mb the page not found error pops up. Using the same pc using standard dial up or adsl from home works fine with large files. large emails, ftp all work fine through the firewall. Only large files outbound are affected. Is there a special setting which controls this? Regards Elbert van Bommel Andico Australia
