I'm having problems in moving the server I dial into from being an old-ish BSDi system to a FreeBSD system. Both systems _seem_ to operate the same way, but I can't get routing correct on the FreeBSD system. Understand, I'm not talking about my local system, it's the one I dial into that's giving me troubles, so all comments from here on are about either the BSDi server or the FreeBSD server, not my own host (also FreeBSD). The ppp for the old BSDi system is kernel mode, and for the FreeBSD system, it's usermode. Both the servers are on the same local ethernet, and communicate to the same single outgoing gateway. The ppp address for my host (which is static, not dynamic ip) is advertised to the gateway via arp proxying. Both systems seem to stick up the same kind of arp info, and the route (netstat -rn) stuff seems alike, but packets being routed to my host from the gateway are intercepted on the FreeBSD server as if they are destined for that server, and not being passed on to the ppp line. For example, an incoming telnet request gets me a banner from the server (it doesn't make it to my home system). I really want to move to the FreeBSD server, because the old BSDi system has a major bug that's killing throughput. If it would be a help, I could post netstat's and arp listings from the working (but slow) BSDi system and the nonworking (but fast!) FreeBSD system. I can communicate directly the server without any problem. Oh yeah, one last thing, I used sysctl to set net.inet.ip.forwarding to 1, so it would forward packets. I tried setting it to 0 (in case I had the logic backwards) but that didn't help any. Thanks for any hints. Both my home system and the FreeBSD server are running FreeBSD-current. ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@glue.umd.edu | communications topic, C programming, and Unix. 213 Lakeside Drive Apt T-1 | Greenbelt, MD 20770 | I run Journey2 and picnic (FreeBSD-current) (301) 220-2114 | and jaunt (NetBSD). ----------------------------+----------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
