We have a T1 line with a Cisco 2620 router that came a part of a promotion from Sprint our T1 provider 4 or 5 years ago. As we look to renew our T1 service with Sprint they are offering an option that for $35 extra dollars a month for two years, gives us a Cisco 2801 router. We haven't upgraded the IOS on the 2620 since we received it. I'm thinking that it may make sense to go with the new router in order to take advantage of any security enhancements.
I have very little experience configuring Cisco routers. I all typically would do is use the filter to only open up IP addresses and ports to a new web server. We also have a SonicWall Pro 230 in our configuration that is about 2 years old.
With the 2620 and the Sonic wall are we pretty secure or should I upgrade to the 2801? Security is my main concern. I don't want to leave ourselves exposed to unnecessarily.
