Router and a firewall in 1 device or 2 seperate devices?
Posted on 2013-01-23
I've read quite a lot from Experts and the net but am still falling short on a little more direction.
Here's the scenario that I've inherited:
There are 3 sites connected with a couple of different broadband providers. There's an installation of ZeroShell software firewall at each location and a couple of Linksys RV082 routers making site-to-site connections.
I want to replace ZeroShell with a hardware firewall solution and replace the Linksys routers. I would like the ability to add 2 connections at each site for redundancy down the road. I need site-to-site vpn and would like to offer my users software vpn connectivity.
Site 1 has about 10 users and I want to plan for that number to double within 2 years.
Site 2 has about 50 users
Site 3 has about 50 users and want to plan for that number to grow by 10 - 20 in the next year or 2
There could be a Site 4 added this year and possibly a site 5.
I've had the thought to throw the Linksys routers in the trash, delete the ZeroSheel firewall, and add a hardware router/firewall at each location. Specifically, I was thinking about 1 hardware device that performs both routing and a firewall, such as an ASA.
What do you think about having 1 device opposed to having a router and firewall seperately?
