Masquerading with dsl

English Network/Internet

Dear support,
I followed all howtos, but NAT form LAN to ISP doesn’t work.

(LAN_comp)------>(eth1 LINUX_comp eth0-dsl0)------->ISP

Setting up DHCP-server from YAST gives an error, so I run it manually. All pings well in LAN.

How should I set firewall zones when i have dsl0, eth0 and eth1?
Is that right?

IP forwarding enabled
echo 1 > /blabla/ done

What I’m doing wrong?
Help somebody please! Thanks a lot…

You need on server:
Fixed IP address to the “gateway” network interface, e.g. 192.168.0.1 [OK]
Assign dsl0 Internet interface to the firewall’s “External Zone” [OK]
Assign the gateway interface eth1 to the firewall’s “Internal Zone” [OK]
IP Masquerading check Yast → Firewall > Masquerading is activated and nothing in Redirect Requests [is that OK]??

You need on client:
Static IP 192.168.0.6 [OK]
Routing like in this Pic but set to 192.168.0.1 [is that OK]??
Nameservers from your ISP like in this Pic or will not find internet sites [is that OK]??

Yeeah! It works!rotfl!

Problem was that DNS server in LAN_conf was my LINUX_comp, but it has to be the same that i get from my ISP.

Thanks swerdna, I’v seen your post after solving, but it helps too, on clarifying understanding.
rotfl!
