One issue is that subscriber lines usually are ADSL2+ over here. I have researched the above solution a while back when I needed to decide whether to use a Linux PC as a router at work or get a Cisco. We now have the Cisco 3725 with external Thomson Speedtouch 510 modems in the "spoof" mode that Koos referred to. We would like to move on to ADSL2+ but I have tried several of those new-firmware Thomson modems (546, 780 etc) and they all fail after one or two days, with the same overflowing NAT table problem (I suspect). This is because in the new firmware, even in spoof mode, the NAT engine is always present in the path :-( Of course the Cisco cannot use PCI modems. When someone on the list knows about a current ADSL2+ modem that still can perform like the old Thomson modems in "SIP Spoof" mode, I would really like to know. (the modem maintains the PPPoA connection and connects to the router over a point-to-point ethernet link, acting kind of like a bridge) Rob _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
