Original message: Hello. I installed FreeBSD with the main intent to use it as a gateway/firewall between my LAN and the Internet. I choose 3.3-RELEASE and set up everything on a 486-based machine running at 66 MHz with 16 MB or RAM, but I wasn't able to get connected to my ISP. I read the FAQ, the HandBook, the man pages, the Pedantic PPP Primer, some RFCs and anything else I was able to find, but I didn't get out of it. I asked my ISP, but after one month the only thing they were able to suggest was to upgrade my system. So I'm asking for help here as a last resort before switching to Linux, which is known to work with my ISP, although I think it wouldn't run as smoothly as this devil doing the other tasks this machine has to do. I've tried both kernel pppd and user-level ppp, with similar results: the modem connects and finishes its handshake, then the game is up to LCP which for some reason either doesn't terminate or fails to start the next layer. I'm reporting both logs in the hope someone can make something out of it. My best choice would be ppp, due to its built-in nat and filtering capabilities, but if that is not possible I'm prepared to revert to pppd. In case it matters, this box works right on the LAN side, since it correctly provides DNS, DHCP, WINS and SMB to the other stations I have. Bye & Thanks av. In the meanwhile I found out additional info: I have to use active mode, since my ISP has probably put his side to passive; when my LCP first send its SendConfigReq, it trigger the other side to start. I keep receiving Config Requests from my ISP and my FreeBSD box keeps ACKing them; also it never gets ACKs from the other side. What I ***THINK*** happens is that the packets I sent get discarded, otherwise my ConfigReq should either be ACKed or NACKed, and I should get only one request from the other side, since my box immediately sends an ACK. In case it matters I see I get a few frame with bad FCS just before I get my first ConfigReq from the other side. BTW: The computer I'm using to connect to the Internet in the meanwhile (running with OS/2 4.0), just show the correct behaviour in the logs, i.e. a ConfigReq in both direction and the corresponding ACK from the opposite side, so I don't think it's the ISP side which gives troubles. Has ppp changed in the latest stable branch? Or has it changed in the soon-to-released-if-I-understand-it-well 3.4? Bye & Thanks again av.
