Solaris 10 as Router...
Hi, I want to build a whole network on my own, but i see its not quite simple. I have a Dlink DSL-320T router for an ANNEX A ADSL connection.

A here is the first issue:
When i connect to the DSL-320T modem the modem get me an ip thru DHCP 192.168.1.101 (Ip of modem is 192.168.1.100). But after the modem connect to the ISP provider it gives to the rtls0 interface a ip like 83.4.204.22...

The other interface on this machine is bge0 with static ip 192.168.1.1

How do i make that PC1 can connect to the internet via the modem? I can see the bge0 but not the 192.168.1.100 modem.

I already made:

#svcadm -e ipv4_forwarding -u
#svcadm -e ipv4_routing -u
The output from "routeadm" shows that routing and forwarding is enabled.

Please help.

Where is your default route pointing to? Also check irst if there's any mismatch of your speed/duplex settings between your system and the switch.
Your netmasks should be specified correctly too. We need more output from the system to analyseSmilie

So i done a manual sys-unconfig Smilie

unplumed bge0 and left only rtls0 for the modem connection.

The rtls0 interface is right now the primary interface and configured with sys-unconfig as DHCP.

The modems ip is 192.168.1.100 and after connecting to it a get an outsource ip fro my provider. But my internet connection doesnt work on solaris.

Ive put in the resolv.conf:
nameserver 192.168.1.100
nameserver 194.205.152.35 #DNS from my provider

and it still doent work.

I tried to plug in rtls0 a configured router and the internet works, but why dont on the Dlink modem???

It seems your DSL modem is giving your public IP address to the rtls0 interface. All of the remaining addresses are not routable to the Internet so you will need either to configure the modem to act as a router (if supported) or implement NAT in the Solaris box.

So until u connect to ISP u have ip address 192.168.1.101 which was given by modem but after when u connect to ISP u have 83.4.204.22 right?
Let us see your
ifconfig -a
cat /etc/nsswitch.conf
cat /etc/resolv.conf
cat /etc/default.router
and also netstat -rn before connecting to ISP and after.

Troubleshoot this like this, for now forget abount client PC, first try solve modem side that Solaris ownself must see world, after what providing internet to client PC s is easy ..

Before geting the new IP a can access the modem and ping it too, also the LAN network from the other interface. But after geting the ip from my provider, a can not ping the modem or google or something.
