My situation is > - Micron Pentium 133 running Red Hat 6.2 (2.2.14-5.0) > - 2 Linksys NC100 V2 10/100 Network Anywhere cards (tulip driver > compiled from Donald Becker's site last > month) > - CopperRocket 201 SDSL -> eth1 > - 10/100 hub -> eth0, 1 W95, 2 W98 machines I have solved the problem. After many other configuration changes to the Linux firewall, I decided that the problem was outside the Linux box. The sites http://www.dslreports.com/tweaks and http://www.helmig.com/j_helmig/speeddif.htm were particularly helpful. What fixed the connection speed was setting, in the registry of the client PC's, the value HKEY_LOCAL_MACHINES\System\CurrentControlSet\Services\VxD\MSTCP DefaultRcvWindow to 65535. It may be that the MTU settings could be optimized as well, but that's more complicated due to the number of TCP/IP bindings that one must sort through, and now I am seeing around 370-380 kbit/sec from all the PC's on the internal LAN. The values in the registry seem to be left over from Dial-Up Networking, or perhaps my previous foray into Microsoft Internet Connection Sharing (ICS) or setting up the LAN. -- John Haggerty internet: [EMAIL PROTECTED] voice/fax: 631 344 2286/3253 http://www.rhic.bnl.gov/phenix/computing/online/oncs/people/haggerty/johnh.html _______________________________________________ Masq maillist - [EMAIL PROTECTED] Admin requests can be handled at http://www.indyramp.com/masq-list/ -- THIS INCLUDES UNSUBSCRIBING! or email to [EMAIL PROTECTED] PLEASE read the HOWTO and search the archives before posting.
