Need to Block some application port on router.

Hi All

Let me explain my problem actually we have two different networks which are connected to separate fast ethernet interface on the router.

One network blongs to our LAN and second network blongs to WAN(we have some application servers on the wan network) now I have one application server on WAN network which is accessible from LAN by specific port and I would like to block some application ports on router so other than LAN user no one else should be able to access that application port.

All I need to configure is to allow only LAN user to access application server and other user's should be blocked to access.

Re: Need to Block some application port on router.

Hi,

with the info you provided there is only a general advice:

Use IP extended access list

see http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/ipras_r/ip1_a1g.htm#1078593 for details.

Regards,

Milan
