cFosSpeed 2.13 Beta 1101 - High-Speed DSL-Treiber

cFosSpeed ist ein High-Speed-ADSL-Treiber, der laut Hersteller eine Erhöhung der Datendurchsatzrate durch intelligentes Management der Verbindung (Traffic-Shaping) und einer individuellen Einmessung des Anschlusses ermöglicht.

Changelog:

Added firewall functionality. It's off by default. You can switch it on in the HTA dialogs. This could be useful for x64 users, since there are few firewalls available for that platform.

cFosSpeed firewall is only designed to protect you from the basic threats like malformed packets, source routing and known insecure open ports. Ingress/egress filtering is only in place for WAN (i.e. dial-up), but not for LAN (i.e. router) ports to protect you from IP spoofing. The firewall tries to stealth your PC as good as possible (i.e. make it hard to find out that a live system is at your IP address.)

You can tighten and/or change the firewall rules like you see fit. Have a look at settings.ini (or "spd filter") for the active rules and the explanation in http://www.cfos.de/speed/documentation/filter_exp.htm. "spd fwstat" will show a count of blocked packets and the rules that caused the blocking. FWLOG.TXT contains a dump of the packets.
If your method is set to PPPoE, cFosSpeed will now limit the MSS to 1452, which is the maximum MSS for PPPoE anyway. The difference is only appearant with a router, where the MSS to the router is 1460, but afterwards only 1452. Thanks to thefonz for pointing that out.
Removed filter_expressions.txt from distribution. See http://www.cfos.de/speed/documentation/filter_exp.htm instead.
