Thread: Bridge Network issues
i have server eth0 (7 port lan switch), eth1 wan , wlan0 wireless pcmcia.
have wlan0 in master mode have work access point. have router plugged in eth1 wan. server has full network , internet access. if log in access point (wlan0) network, no internet access. did experiment weekend , found if plug router in (eth0) lan switch server gets full network , internet access, access point still same. if plug router in wan said server works 100% network, no internet in lan switch. feel issue id either ip forwarding or bridging. server acting right or give print out of ifconfig, iwconfig , network/interface file.
there try or else needed issue?
oh iptables fine too. same , out them running (i used iptables ubuntu gave on bridge network page).
ifconfig
