I just recently moved from a cisco 1720 router and a pix 515 to a cisco 2851 ISR and ASA 5520. We also have a DS3 coming in from our provider. We use to have 2 bonded T1's on the 1720 since the upgrade we have added 2 more T1's. So now we have 4 bonded T1's in the 2851 from what I have read I can bond and additional 2 T1's on the 2851 giving me 6 bonded T1's. After upgrading we have been adding clients so the upload and download has pretty much stayed the same for the most part. My question is after adding 2 more T1's to get 6 bonded whats next? Do I have to purchase more firewalls and some kind of load balancing? What are my choices? Thanks in advance.

It may be worth moving to a different type of connection altogether. What is available will depend where you are and what you budget is, but for example we have a 100 Mb/s direct link out to the internet. This would just plug into an ehternet port on your firewall and you wouldn't even need the router.

Alternatively, most countries have pretty good DSL offerings now adays so if you can get an 8 Mb ADSL line you could do some load balancing and send some traffic accross an ADSL/SDSL link, keeping your T1s as a more reliable backup. You could get an ADSL / SDSL hwic that would integrate into your existing router.

I have a DS3 coming in but only a certain amount of channels turned on. If I read right this should give around 30 something mb/s right? The way it is now is the DS3 comes in and then terminates at a mux which splits it up into RJ-45 connections. Is there a different connection that I can use coming from the DS3 so I don't use up so many ports on my router?
