Juniper Networks Netscreen Support for Multiple ISP's
Posted on 2007-08-09
I am considering the purchase of a Juniper Networks Netscreen-25. However, after reading through the documentation I'm still slightly confused about some of the Netscreen's capabilities. So here's my question:
I'd like the ability to support multiple ISP's. We currently have a T-1 supporting our office of about 25 people. The T-1 also supports a IPSEC VPN with our remote office. Generally, the T-1 works well - but it gets bogged down with "junk" traffic (YouTube, internet radio, etc...). We're in advertising so, believe it our not, YouTube and similar sites are actually work-related when performing research and what not - blocking them isn't an option.
Is it possible, with the Netscreen-25 to use multiple ISP's (T-1 for mission critical application traffic, etc... and Cable or DSL for web browsing)? Are the routing capabilities of the Netscreen-25 able to utilize these multiple connections? I'd rather not have multiple gateways on my LAN, I'd like all clients to point to the Netscreen and have it handle the routing. Specifically:
1. Can the Netscreen send traffic to a specified gateway/ ISP based on protocol? (http to one ISP, and SMTP to another ISP for example)
2. Can the Netscreen route traffic to a specified gateway/ ISP based on source IP address? (192.168.0.2 would use the T-1, all other hosts would use the cable connection)
Also, I'd like to know how complicated implementing any of the above mentioned scenarios would be.
