I'm attempting to install OBSD 3.7 sparc on a Sparcstation 20. I've been through installs numerous times on 20's, 2's, and an IPC using previous OBSD versions. Currently, I only have one install method -- floppy. I could conceivably set up a netboot install or wrangle a CDR drive if need

OpenBSD "Visible" Bridge and NAT box -- strangeness and questions

2005-07-06 Thread Jim Fron
I have an OpenBSD/Sparc box that I'm using for NAT at home. le0 is the LAN, le1 is the cablemodem. I recently purchased a wireless AP, and would like to add that to the internal network. However, I am paranoid, and, even though I've enabled WPA and hardware address restriction on the AP, I stil

Good news! I'm half-way there. I took Camiel's patch to bridge_input() in if_bridge.c ref: google:"bridging vlans on a single interface" and modified it slightly so that the source interface would not get rewritten if the destination mac address matches, period. (no longer vlan-specific) T

bridge changes traffic interface for pf, but not for tcpdump

2005-07-06 Thread Jim Fron
Okay, here's the deal: when I bridge two interfaces, one of which has an IP address, traffic from nodes on one side to the other passes through pf just fine, all rules matching properly. Traffic TO the OpenBSD system itself hits pf rules for "in" on "le2," and "out" on "le0" regardless of whic

I was testing my pf.conf rules, and I ran across something rather odd while sending odd ICMP frames. I wrote a quick app to send raw ICMP/UDP/TCP frames, and ran it from an OSX box to send raw ICMP. I ran simultaneous tcpdumps on the OSX box sending the frame, the OpenBSD (-stable, as of a co

This is an intriguing problem that certaiinly is going against everything I know about how pf and bridging is supposed to work on OpenBSD. Anyhow, I have come up with some things that might help you ascertain what is going on with the firewall. I reread your initial emails and follow ups to e

Okay, I can get my bridge and pf rules working if I need to, but I'd still like to understand WHY they work they way they do. So I ran some test cases. My configuration is this: OpenBSD/Sparc (SS20). I have one external interface, and two internal interfaces. There's NAT to the external, but

A helpful person on the PF list said he has a similar setup, but does not experience the problem I'm having. So I'm starting to suspect it might be an SBUS/Sparc-specific problem. I'm working with OpenBSD/Sparc on an SS20, and, if it makes any difference at all, my interfaces are lebuffer and

I found this: http://openbsd.automagic.org/plus.html "Apply bridge filter rules to frames destined for the local machine, so a single-interface bridge can do filtering and tagging." And then searched on that phrase, and found this: http://www.monkey.org/openbsd/arch
