When EMC decided to shut down development and sales for RainConnect, it left a tremendous hole in our ISA firewall armamentarium. RainConnect was our only on-box option for supporting multiple ISPs using ISA firewalls. At this point there are only two options:
- Use the Network Engines NS series ISA hardware firewall, which comes with built in ISP failover
- Use a device in front of the ISA firewall that provides support for multiple ISPs
You can find out more about the Network Engines NS Series hardware ISA firewall over at www.networkengines.com
For an interesting discussion on multiple ISP support using other methods, check out this thread over at the ISAserver.org Web boards at http://forums.isaserver.org/m_2002020401/mpage_1/key_/tm.htm#2002022497
