Hello, can somebody explain me what I'm doing wrong? I'm running OpenBSD 3.4 with two 10/100 NICs with Realtek 8139.Box (P133, 32 MB RAM) is configured as a no-IP bridge with some simple pf rules.
In my home network with an old 10MHz hub and Cisco router everything works fine. PC <---crosslink -->rl0 OPENBSD rl1 <----> HUB < ---> CISCO <----> Inet When I move this PC to different network with D/link switch and WAN/LAN router the strange behaviour occurs. PC <----->SWITCH<------>rl0 OPENBSD rl1 <---crosslink--> ROUTER <---->Wireless receiver<----> Inet Ping and POP3 to external places works OK, some web pages too, another WWW starts downloading and then stops. I hope there is no DNS error. At first I've tried change NICs,cables,decrease media speed but no luck. When I disable pf, all data are passing thru the bridge without problem in any combination of NICs. Pf.conf contains now only rules for passing all on both interfaces. I don't think there is problem with the rules,because at home is all traffic OK. What I'm missing? I can supply you with more data,I don't know where to start. Can help some TCPdump? MTU,no-IP or an old (slow) machine problem? Should I try router configuration? Actually I don't need router, all HW is on the same private C-network and ISP on the ROUTER NATed public address into interal network. Does pf change in packet? ISP said me,that this is maybe the reason for problems.I can't still imagine why some pages are downloaded and some not. Thanks Mira
