VLAN inquiry

Unanswered Question
Apr 20th, 2009

hello anyone who could assist me. I have attached my diagram and configurations as well. Just want to know if I did correct configurations for my devices? If yes, how come my colleagues who is handling the FW can not see R1(10.20.25.66) he can see VLAN2(10.20.25.65) and i can ping from the SW R1? Is there any wrong with my configurations? thanks

I have this problem too.

Hi Korbenda,

It looks like you don't have any routes on R1.

Try adding:

ip route 10.20.25.60 255.255.255.252 10.20.25.65

Unless this firewall is your link to the internet, in which case it should be

ip route 0.0.0.0 0.0.0.0 10.20.25.65

Hope that helps.

Please rate any posts you find useful.

hi,

I was able to ping R1 from the sw but not from the FW, and why is it ip route 10.20.25.60 255.255.255.252 10.20.25.65? R1 is part of the VLAN.

Is my configurations on SW, R1 and S1 are correct? if yes, what route are missing? thanks!

Hi Bhargav,

Are my configurations correct for the SW, R1 and S1? so you are saying that it just a routing issue? Do I need to configure routing to the SW?

Hi Korbenda,

As I said - you need routes on the router - else how does it know where to go to get to your firewall?

Add the following to R1:

ip route 10.20.25.60 255.255.255.252 10.20.25.65

The Firewall will also need a route into the network if it hasn't already - please copy the routing table here (Sanitise any public IP addresses) and we can have a look for you.

Nick

Hi, i have already add the route you mentioned and from FW it can already see the router. Now, the admin told me to add another route to the router so that I can access it from the internet. Do I need to add another route? is it 0.0.0.0 0.0.0.0 10.20.25.65, thanks!
