I need to block some tcp ports for certain switch ports (block one network access by those ports). But when ever I need I should be able to disable the rule and enable access and again enable the rule (to block the port again).
At the moment I have Linksys SRW224G4 and look at IP based ACL and look like I could block the ports.
But so far I could not find a way to disable the rule temporarily other than delete the rule.
What I'm trying to do is block access to few ports. Let say port 80, 8080, and 25. But when ever need to access I need to enable/disable the rule. Enable / disable the rule have to be done using script or RADIUS server (prefer to use a script) since this task (enable / disable) to be done by none technical users.
Am I missing something on the SRW224G4 switch or is there new switch I could use for this purpose?
Other issue I can see when ever I login to Linksys switch via command like goes to a menu.
Is there anyway I could issue commands like CISCO?
Or could I use small CISCO managed switch to do this? I'm not very familiar with CISCO switches other than configure few few routers and PIX.
I'm not intend to use a firewall hear since at the moment there is no way I could change the gateway or the IP addresses in the network.
I do not have one of these switches in front of me, however it sounds like you cannot edit an active rule.
This is fairly common in my experience ..., since the order of the ACL is most important. It is not always a bad idea to create a second ACL and then delete the first one and re-apply the second one.
With Cisco you have a lot more flexibility, features, and functionality; you can get yourself out of, and into any trouble! Also configuration is done via a very smooth GUI tool called Cisco Network Assistant.(CNA). Of course scripting and CLI work well too
With ACLs, the order will always be important and do not forget the 'unwritten deny-all' statement at the end of the ACL.
The menu will always come up when accessing the console port or telnet. No way around this ...
CLI is not supported on these switches, and I would not want to see you install and unsupported installation.
