Cisco 2620 Router and Sonicwall TZ170EN
Posted on 2006-06-20
I have a Cisco router with dual T1's. The fast ethernet goes to SonicWall TZ170. My ISP provided me with 4 blocks of ip ranges (2 on each T1). I tried to use the other blocks of IP's on the TZ170 but not able too (one block works). The subnets are different. The Cisco router is doing load balancing only. My thinking is to take the load balancing off from Cisco and move it to TZ170. Then both T1"s can get recognized and I can use the ip ranges. Also, I want to setup redundancy for the T1's by having them come from two different ATM's. They already come from two different CO's but end at the same ATM. Any suggestions on how I establish my goals. Cisco router is managed by the ISP. TZ170 is managed by me.
1. Make the additional Public IP's usable
2. Provide redundancy for the T1 connection
3. Control the T1 usage
