ADSL, firewalls and VPNs?!?

By cymro ·
Our company is interested in ADSL. How easy is it to configure a router to dial out and act as a firewall? You can get out of the box solutions but how good are these?

What does configuring a VPN involve? Not thinking of doing this myself, just interested.

I know this is not what you asked, but why ADSL and not SDSL?

Keep in mind that ADSL has a much lower upload speed than the download speed.

Since you are looking to set up a VPN, I assume that you would be uploading data more than a typical residential user, who are the primary market for ADSL.

I'm not a VPN expert myself. However, just search the site hear for VPN and you should find plenty of articles and discussions.

A couple of years ago, there was even an article that had links to all the other VPN related articles on the site.

Don't ignore the downloads page as there are a few VPN information downloads.

Not enough information

by jdclyde In reply to ADSL, firewalls and VPNs? ...

How many users?
How many locations?
What applications will be used over this VPN?
How many concurrent VPN users will you have?

And the question has been asked, "Why ADSL?". A business grade cable modem is faster, much faster.

Setting up a router to do this is not difficult, depending on the router. An actual firewall is still a good idea, and I would not run an internet connection into a business without one.

sonicwall, firebox, cisco pix are all good products, but not the only ones. Sonicwall and firebox are graphical and easy to use. Pix, you will have to learn.

pptp is often much easier for a user to use, just depends on the level of security you are looking for with your applications. You can have the firewall handle your vpn connections, and also have a DMZ port to segrigate your servers on.

vpn, many of the firewalls will have a client if you chose to go that route. SSH sentinal my be way over the heads of your end users.

If this all sounds like blahblahblah, look at your service provider. Some will offer managed solutions where they will do everything for you. I think it is better for YOU to do this in-house because adding this skill increases YOUR value to the IT community.

Good luck.
