Hi,

 

Im trying to route between two networks. The two networks are

 

Network 1 - existing exhibition centre network providing internet access

Network 2 - a new temporary network we are creating

 

Network 1 is connected to the router ethernet interface 0/0. The port IP address is 192.168.1.10 - 255.255.255.0. 

Network 2 is connected to the router ethernet interface 0/1. The port IP address is 172.16.0.1 - 255.255.0.0 - This network needs to support about 2000 IP addresses.

 

The default gateway on network 1 is 192.168.1.1 - 255.255.255.0

 

Network 2 needs access to the internet. How should my routing table look?

 

Currently I have added

0.0.0.0/0 Static 60 0 192.168.1.1 Eth0/0

 

This allows me to ping the world from the router though the gateway on network 1. The problem is devices on Network 2 cant access the internet. What do I need to add to my routing table?

 

PS as you probably have guessed im very new to networking!

 

Thanks in advance for your help

Hi,

 

your MSR router should know about Network 2 because this network is directly connected to the router interface.

 

Problem seems to be that your another router which has 192.168.1.1 ip address (thats the default gateway from MSR point of view) doesn't know how to route back to your Network 2. So you have to add static route on this 192.168.1.1 router to route to Network 2 destination.... 172.16.0.0 255.255.0.0 192.168.1.10 (destination/mask/next hop).

Hi Jan, thanks for your reply.

The problem I have is I dont have access to the 192.168.1.1 router. Is there a way I can achieve this using just the other router? I've seen NAT pop up a few times when I've been researching this on google. I dont really understand these but could they be the answer?

Hi, ok if there is no way to add route to second router by you or by authority which manage this router the other solution could be to implement NAT (probably PAT) on your MSR router and translate 172.16.x.x adresses to 192.168.1.10:port.

 

Probably the best would be if you check related manuals for this:

Hi Jan,

 

Thought this might be the case. I'll shall read up on NAT!

 

Thanks again for your help :)
