Re: Allowing traffic incoming

["Joe" <captain at nsimail.com>]

Hello William,

 

Thanks for your response. Now, this is the situation let me make it clearer. Network A has a block of /24 ip addresses and it connects via a leased line to Network B on one of the /24 ip addresses on Network B as the external IP (this is Network A's upstream). Now, Network A is supposed to get it's downstream from Network C (another network) with a /23 and /24 block of addresses via a Simplex ONLY Satellite but Network C cannot access network A. SNMP queries sent to the reciever in Network A by Network C cannot be accessed by Network C owing to somewhat suspected to be a filter rule.  No filters have yet been set and as such the line which has "ANY" is written in all the columns. External Network B can send replies to A. The question is now how to configure RRAS in Network A to allow traffic incoming to A from Network C to pass through. The Do you still want me to send a picture?

 

 

Thanks,

Joe

Hi Joe,

 

Assuming you are using NT 4.0 (W2K Server is slightly different), then under RRAS, select: -

 

<IP Routing> <Summary>. Right click the interface you are interested in and select <Configure Interface>. You will see two buttons <Input Filters> and <Output Filters> If you HAVEN'T set any filters, you should see one line with "ANY" written in most of the columns. If you have already specified filters, you may have accidentally excluded your network. Adjust as required.

 

However, your problem is more likely to lie in your routing being incorrectly set up. Do you have a default router, and where is it connected? What are the IP addresses of your internal network, your default router and your external network? Does your default router know where to find your external network?

 

It doesn't help if your external network can connect to your internal network via RRAS, if the latter doesn't know how to send any replies!

 

Draw us a picture, and we will be better able to help you ;-))

I have a cisco router but i am not using that yet. Presently, i am using the routing feature in microsoft RRAS but my remote network cannot access the main office because of a filter rule on my router. Now i want to allow traffic incoming from my remote network with a   /23 and /24 block of addresses to pass through my router but i do not know where to allow this. I assume it should be under the configure interface dialog box where you see input filters and outpt filters but i'm not sure.

 

Does anyone have an idea about how to allow such a remote network to pass through the routing and ras.
