You'll need to be a little more specific than this. What happens? What are the error messages? Does DNS resolve IP addresses? Can the machine with the ADSL bridge access the Internet?
 
ok. now, i can ping from freebsd to default router. but cant ping from win xp. via freebsd. also freebsd as gateway. how can configure unix to receive ping from windows xp, and pass it to internet?.
thanks.
 
Please provide the information. We cannot help you if we do not know how your network is set up.

We're good but we're not clairvoyant.
 
freebsd pc has 2 nics, rl0 192.168.5.27, rl1 192.168.0.27. also configured as gateway. in rc.conf. and access to internet via adsl modem (pppoe). it can ping to internet site's ip. but another pc windows xp, cant ping internet address, only between freebsd and windows can ping.
i want to access to internet from windows machine. windows pc configured correct.
 
Do you have gateway_enable="YES" in /etc/rc.conf?

You also need to set up your DSL modem to route 192.168.5.0/24 back to the freebsd box. That's assuming the 192.168.0.0/24 network is between the freebsd box and the DSL modem.

i think it is not modem issue.

Yes, it is. Your modem doesn't know where traffic to 192.168.5.0/24 goes to. You need to add that route on the modem.
 
Or use NAT on the gateway if you can't do anything with the modem.
 
ok. also i installed dns. and now it pings to by name. and by ip.
oo yess. pretty f....ng sad.
 
is it important to enable firewall for natd?
options IPFIREWALL
options IPDIVERT
for kernel?.

Not really, you are behind a modem/router that does NAT for you. No real need to run a second NAT or firewall. You just need to make sure the routing is set up correctly.

And you don't need NAT either.

then pls tell me, if i dont need nat. what is pppoe profile?
yes i read pppoe docs, but PROFILE.
is it login, password, ?
 
Dual-homed host. In a dual-homed environment, a PC is configured as a gateway between the local LAN and the DSL modem. With a bridged or routed DSL connection, this gateway can be configured as either a router or a NAT/proxy server. With a PPPoE DSL connection, this gateway would have to be configured as a NAT/proxy server (because the PPPoE protocol won’t pass over

the gateway).

That's usually done in the modem/router itself these days. What modem/router do you have?
