LACP is a link aggregation control protocol, it is *not* a keepalive / link failure detection protocol. If you can move to L3 (routing rather than bridging) then ospf is one way you could achieve something like what you want using OpenBSD (failover + use bandwidth of both links when available via ECMP). But you'll need either an L3-capable switch with OSPF support, or a second box.

Re: Wireless bridge setup
If I remember correctly, bridging only works in hostap mode. Bingo, someone remembered -- and that is correct. In the other modes, MAC addresses of course do not get exposed correctly, and your access point cannot impersonate the other hosts it is required to. It is fairly obvious if you think about it.

Re: wireless bridge with soekris 4801 and seano 2511mp+
Todd, I never tried the bridge without WEP. I could not get the card to initialise with WEP in the soekris. I have successfully initilaised the same card with WEP in hostap mode on my laptop, but not as a bridge. My past attempts to use the card with software WEP in hostap mode have always failed! I can get the wireless bit to work with ibss-master. I have confirmed by assigning an IP address to wi0. I can see that the bridge works as I can see the packets on both sides with tcpdump. However, the bridge with wireless does not work! Is hostap essential for bridging? I'm appending my followup mail listing my experiment, for your reference. Thanks Regards, Anwar. - = I have some more information now. I'm sorry, its a bit long winded, but I thought I'll document my experiment. pf is disabled. ip forwarding is disabled I am completely stumped and will really appreciate any input.

wireless bridge with soekris 4801 and seano 2511mp+
Hi all, Has anybody built a wireless bridge using the Soekris net 4801 and a seano 2511mp+ (wi) minipci card? When I tried configuring wi0 in hostap mode with WEP, it used to fail consistently with the message wi0: init failed. I then tried setting up the card in ibss-master mode. This at least initialises the card. I have tried setting up 2 bridges as: sis0 - bridge0 - sis1 wi0 - bridge1 - sis2 tcpdump on sis2 and wi0 shows that the bridge is working properly, with arp requests visible at both ends. However when I set up another computer sis2 side as: computer1 - wi0 - bridge1 - sis2 -computer2 (192.168.5.3) (soekris machine with no ip assigned)(192.168.5.1) I cannot ping the two computers. ping 192.168.5.1 from computer1 shows the whois packets and the corresponding reply with tcpdump on wi0, but computer1 does not initiate the icmp echo requests. The other way around, ping 192.168.5.3 from computer2 shows the icmp echo requests, but no echo replies. As a sanity check I set up another computer as 192.168.5.100 on a wireless network, and I could ping computer 1 successfully. I then tried setting up an IP address on soekris-wi0, but it did not help. It's almost like the wi0 card is not being initialised correctly on the soekris board. I swapped the wi0 cards with another I use on my main laptop, to check that the wi0 hardware was OK. The kernel is GENERIC, but rebuilt with the latest patches for 37. Any ideas would be appreciated. The dmesg and startup capture, hostname.* and bridgename.* are appended.

wireless bridge router/firewall
I recently got cable. The modem is installed on the third floor of the house. We have a wireless router which allows me to connect my laptop, and we have an xp machine and a ps2 hooked wired to two of the four wired ports on the router. I wanted to build my own router/firewall but the modem is in someone elses room and they don't want to have a machine sitting in there. What I want to do is somehow build a box that is a router/firewall but connects to the internet using the wireless signal, so I can set up my own router in my room in the basement and connect a bunch of wired computers so I don't have to buy wireless cards for everything plus so I can have my own dedicated firewall. This is basically a standard or bsd dedicated router/firewall box, but which uses the wireless to get to the internet instead of a second network card. Can this be done? I looked into these wireless bridge things but I was wondering if I could do something like I've described with a bsd or gnu/linux box with wireless card and a network card which is plugged into a switch like a normal bsd or gnu/linux router. I searched and didn't find anything on this topic. I know this isn't the most ideal setup for a home network, but its all I got for now. At least my part of the network will be firewalled off from the windows side. Thanks.
Re: wireless bridge router/firewall
*Bridged*: The easiest, unfirewalled Get a switch and a wireless bridge (Like senao /engenius sl2511) Connect the bridge to the wireless router and to the switch and you're done. Cost: 100 euro Or: Get an openbsd box with ethernet and wireless card, bridge both interfaces and connect the wireless interface to the wireless router. Connect the wired interface to the switch where you also connect the rest of your equipment. Here you could set up a bridged firewall with pf. * Routed * Get an openbsd box with ethernet and wireless card, instead of bridging, configure NAT between the two interfaces, connect the wireless card to the wireless router in client mode. Connect the wired interface to the switch togheter with your equipment. Things to read: pf manual man ifconfig man brconfig man hostname.if and some more... If you know how to do it it's five minutes work. If you don't, it's some homework. Zen Lunatic wrote: I recently got cable. The modem is installed on the third floor of the house.
