Hi guys,

I have a Linksys WUSB11 v2.8 802.11 USB wireless adapter on a fresh OpenBSD
4.2 install. It is recognized as an atu0 device. Internally it works great.
I can ping all of the IPs inside the gateway (and ping the gateway) and
browse to internal web sites, etc. Externally, I have no connectivity on
atu0, but I can get outside on my wired (fxp0) interface. Here's the
relevant portion of my ifconfig with the wired (fxp0) interface down:

fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
lladdr 00:50:8b:67:04:60
groups: egress
media: Ethernet autoselect (none)
status: no carrier
inet 192.168.0.254 netmask 0xffffff00 broadcast 192.168.0.255
inet6 fe80::250:8bff:fe67:460%fxp0 prefixlen 64 scopeid 0x1

atu0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
lladdr 00:0c:41:56:f4:30
groups: wlan egress
media: IEEE802.11 autoselect (DS1 mode 11b)
status: active
ieee80211: nwid NETGEAR chan 11 bssid 00:0f:b5:c5:31:7e 87%
inet 192.168.0.127 netmask 0xffffff00 broadcast 192.168.0.255
inet6 fe80::20c:41ff:fe56:f430%atu0 prefixlen 64 scopeid 0x4

I've tried adding atu0 to the 'egress' group, but still no go. Any ideas?

Thanks,
Brad

These are in the same subnet, this won't work. You might like

Wow, a nabble post with sufficient information to spot the

Can't you bridge them or create separate subnets and route them?

Is trunking the purpose here?

Just wondering....

It was just an experiment. I was trying to do some funky routing through the
wireless interface. I'll play with it some more. Thanks to all for the tips!

failover trunks are quite good for this situation (depending on how
long your switch takes to notice the move). Separate subnets are another
option but means doing more (and losing active connections) when you
change between wired and wireless.

You might use bridge(4) for an access point but that's somewhat
