Figured it out... I had no ip unreachables set on the interfaces on the Ciscos, which was preventing Path MTU discovery.

Everything appears to work OK, but when transferring files from the Cisco network to the FW-1 network, Windows machines get the following error: The specified network name is no longer available Files can be copied OK from the SecurePlatform R55 side to the Cisco side. The official MTU values for both services are 1500. Setting the MTUs lower on the Cisco routers doesn't seem to help (even with ip tcp adjust-mss 1452). We don't have this problem with other VPNs (Cisco Concentrators and other FW-1s). Anything else we should try? thanks Chris ================================================= To set vacation, Out-Of-Office, or away messages, send an email to [EMAIL PROTECTED] in the BODY of the email add: set fw-1-mailinglist nomail ================================================= To unsubscribe from this mailing list, please see the instructions at http://www.checkpoint.com/services/mailing.html ================================================= If you have any questions on how to change your subscription options, email [EMAIL PROTECTED] =================================================
