I'm looking for something to use as a proxy server. What do you guys suggest? There will be 4 or 5 pc's connecting to it for internet access and I must be able to use a 3G card for internet connection as well.

You can use ipfire or endian firewall both would be easy enough to customize and configure.

FreeBSD is by far the best tool for the job, or pfSense if you're not so technically inclined.

You will need to have two NIC's, or run it in a VM with both NICs on the same adapter.

Works beautifully, and can be managed remotely by the built in web GUI or by SSH

Get a 3g Router (with or without ADSL support) and use Smoothwall.

Been using it for a few days now and all I can say is Awesome!

I run a Mint Linux box with Squid 3. Works well, and I use VNC for remote desktop. You can also use Webmin to have a web interface to easily access squid configurations and do linux updates. (it has loads of other addons too!)

I use Firestarter to set up the iptables' rules. It's rather straight forward and works fine for my purposes.

ClearOS

However, if you are going to be using a 3G card, you are either going to have to know (or know someone) who knows how to customize the server for that, or use a 3G router or 3G USB router.

Wilco, I recently deployed two ClearOS solutions. At one site, the client had a Telkom Tidus line for internet access, and a domain hosted with MWEB. Due to the peering issues, between MWEB and Telkom, all SMTP and POP3 data would be routed with high latency internationally.

To temporarily circumvent this, I used an old Linksys Ethernet 3G router that the client had, and manipulated the ClearOS server's routing table to redirect MWEB, SMTP and POP3 data over the 3G router with a prepaid SIM. Thus casual web browsing would be done over the Tidus and data intended for MWEB's mail exchangers would be routed over the 3G router. Fortunately MWEB and Telkom is now peering locally and I could remove the 3G router.

My point here is that since ClearOS is Red Hat based, you can easily manipulate the server to suite your requirements, additionally you could connect a E220 3G USB modem and connect to the internet via wvdial, maybe even introduce a small shell script to monitor and reconnect the 3G on demand.

ClearOS is an excellent feature rich distro and it can be configured via a well designed web administration interface.
