7102 Setup

[Ryan_G]

Hi All

I am a newbie to routing but have just purchased a 7102 with dual ADSL2+ cards in it. I would like a little assistance on how to setup it.

Firstly I have 3 internal VLANs.
192.168.1/24
192.168.2/24
192.168.11/24

I want ADSL 1 to services subnets 1 and 11 and ADSL 2 to service subnet 2. This a staff / student environment with subet 1 being staff and 11 being servers, and subnet 2 students.

I also have a 5406 Switch with routing enabled.

1. What VLANs do I put the eth 0/1 & 0/2 in and how do they connect back to the ADSL connections themselves. Do I have to setup routing between port eth 0/1 and ADSL1? and same for 0/2 and ADSL2.

2. What Routes need to be setup on the 7102
3. What Routes need to be setup on the 5406
4. do I need to setup NAT on the 7102?

5. Anything else useful that i should know.

Thanks in advance.

This is definitely possible.

What I would do is create 4th subnet which communicates between the 5406 and 7102dl only, e.g 192.168.10.0/24.

Create a new VLAN on the 5406, assign it untagged to a port and give it IP address 192.168.10.1/24.

On the 7102dl give eth 0/1 an address of 192.168.10.2/24.

Next you could either use RIP or static routes between the two.

For static:
5400: ip route 0.0.0.0/0 192.168.10.2
7102: ip route 192.168.1.0/24 192.168.10.1
7102: ip route 192.168.2.0/24 192.168.10.1
7102: ip route 192.168.11.0/24 192.168.10.1

Once you've got your ADSL links up, I would then go through the firewall wizard on the 7102dl web-interface (did I mention it's the best web interface of all time?). This should set up a basic NAT setup for you and at this point all Internet bound traffic should work and will be directed out one of your ADSL interfaces.

To then move on to the final step of having certain traffic go out each ADSL interface, you will need to read the chapter on Policy Based Routing in the 7102dl user guide which gives some great examples on how to go about this.

Ive got the Advanced guide to router and the basic guide. Which chapter are you referring to? Do you mean ACL's? I cant see a chapter on policy based...

Thanks
