IPS 4240 - configuration

hi

I have IPS 4240 - ver 5.0.2 . I am not able to start admin console from any other host other than those on the same network (class C). I have configured allowed host properly in the config. Please suggest.

Please direct me to any url where the setup/configuration has been explained in detail.

thanks.

regards

Re: IPS 4240 - configuration

Please do run setup and try to modify the access list like below.

For exaple to allow network in the 192.168.1.0 255.255.255.0 range:

Modify current access list?[no]: yes

Current access list entries:

[1] 10.0.0.0/8

Delete:

Permit:192.168.1.0/24

This is documented here:

http://www.cisco.com/univercd/cc/td/doc/product/iaabu/csids/csids11/cliguide/cliinit.htm#wp1031114

The other thing to check is wether there is some sort of firewall/filter in the path from the other network defined to the sensor for https port you configured.

Hope this helps.

Re: IPS 4240 - configuration

Also ensure that your default gateway is correct.

When running setup the ip address, netmask, and default gateway are entered in this format:

/,

example:

10.1.1.30/24,10.1.1.1

If the default gateway is not configured correctly, then the sensor will be able to talk with other hosts in the same network, but won't be able to send packets to any other network.

Compare the default gateway setting on the sensor with the setting on other machines in the same network.

Re: IPS 4240 - configuration

Thanks all.

Finally found the problem. It was due to IP clashing with my sniffer laptop which was put last week for temp usage.

Can anybody say, what would be the best way to collect and analyse the events? Is it possible to set email notifications? Thanks again.

Re: IPS 4240 - configuration

Depends on the number of sensors.

For large deployments CS MARS is recommended for event viewing. It is an enterprise class viewer that can handle large deployments of sensors.

But is also an additional purchase cost.

For small deployments IEV is recommended for event viewing. It handles between 1 and 5 sensors. It is available for no additional charge as part of the standard maintenance contracts for the sensor:

CS MARS does support sending email notifications.

IEV does not yet support sending email notifications (feature request is in review).

The sensor itself does not send email notifications, however the sensor can be configured to send SNMP traps. Many SNMP receiver tools are able to generate email notifications from the SNMP traps.
