Remote Services

[john-lucero]

Is it possible to use a css 11501 to load balance to remote services over the internet through a firewall?

[Gilles Dufour]

yes - the CSS does not care about the location of the real servers.

You just need to make sure your keepalives can reach the server and get back to the CSS.

Then, you need to make sure the traffic you sent to the real server can go through the firewall.

How do the keepalives work? How would I test if they are working through the firewall?

[Gilles Dufour]

the simplest keepalive is a ping.

So, you could try to ping the remote device from the CSS.

If the firewall manager does not want to allow icmp traffic, you can use tcp keepalive or http keepalive.

The CSS will then open a tcp connection to the remote destination.

You can't really test it from the CSS except configuring the keepalive and see if it works or not.
