Do you have recommendations when using SecuRemote over a wireless network? One of my SecuRemote users is connected to SW Bell via a PPOE connection that is terminated by a linksys hub. He did the following to make it work. 1. Reduce MTU size from 1500 to 1400 on the laptop. 2. Installed latest Linksys software on the hub. The MTU size problem was recognized after small parts of a web page loaded correctly, but large parts did not. SecuRemote authentication was OK. SecuRemote works in a wired network but does not work in the wireless network SWBIS DSL ( requires PPPoE ) Linksys BEFW11S4 NAT Router (includes PPPoE client) 802.11b Wireless Access Point Ethernet switch Win 2k Laptop Ethernet to LInksys Switch Wireless to Linksys access point (56 bit WAP encryption) Integrated V.90 win-modem Do you have suggestions to make SecuRemote work in the wireless home office environment? Here is the user's analysis. "It appears that the SecurRemote software uses DIX style TCP/IP packets instead of 802 style packets. If any other protocol later encapsulates the frame, or tries to convert it to 802 format it will fail. ( DIX has a slightly larger data section that 802.) The solution is to hard code the MTU. I didn't figure out the true limit, I just used 1400." "It also appears that SecureRemote cannot work with 802.11b wireless adapters. I'm not familar with the 802.11b frame details, but I bet it can't handle DIX. SecurRemote is probably only sending DIX format packets and not even listening for 802 format packets. With it hooking into the NDIS layer, it could be doing anything and we have no way to know. This issue should be raised with CheckPoint support." greg _______________________________________________________________ Greg Polanski mailto:[email protected] ADC Telecommunications, IncMSFAX PO Box 1cell/pager Minneapolis, MN [email protected] - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - After June 29, 2001 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Greg Polanski mailto:[email protected] ADC Telecommunications, IncMSFAX PO Box 1cell/pager Minneapolis, MN [email protected] _______________________________________________________________ ================================================================================ To unsubscribe from this mailing list, please see the instructions at http://www.checkpoint.com/services/mailing.html ================================================================================
