Advice on finding a hardware router / firewall solution that will aggregate 2 internet connections
Posted on 2006-07-24
I hope that this description is not too vague but I'm not really sure what I need so I will explain the situation and if any clarification is needed I can provide it.
Our ISP is able to provide us with a 2MB synchronous line with 8 IPs (of which 5 are usable) for a reasonable price. Our plan is to order 2 of these lines to give us a total of 4 MB bandwidth and 10 usable IPs (it's much cheaper for us to get 2 lines each running at 2MB than one 4MB line). We will be provided with (at our end) two ethernet lines which we need to plug into something - this is what I need advice on.
I am looking for a hardware solution which will allow me to:
- combine these 2 ethernet connections into the equivalent of a single line for use with our web server
- provide firewall security to protect the web server
- allow us to set up a second web server and load balance the traffic between the two servers so that when one is not being used so much the other can use the extra bandwidth but if both have high traffic then they should share the bandwidth more evenly
- one of the web servers has a secure certificate - this should continue to work with whatever the new configuration is (I expect I'll have to change the IP address of the certificate)
Can anyone recommend a suitable box that would allow me to do all this (and possibly more things that I haven't thought of)?
