Hi All,<br />
Could someone please guide me on setting up the timeout for an IPSEC Tunnel.<br />
<br />
we have some servers that are present in a hosted environment and an IPSEC Tunnel has been configured between our intranet and the hosting company for remote login and administration of the servers.<br />
<br />
Our company uses Microsoft ISA Server 2004 as a firewall and the the hosting company has a cisco pix firewall. The IPSEC Tunnel has been established successfully, but it keeps dropping almost every 10-15 minutes. Some of our staff use remote desktop web connection on these servers and find it very annoying when the tunnel keeps dopping out every 10-15 minutes.<br />
<br />
Coudl you someone please suggest if there are settings that need to looked into (especially in our ISA Server 2004) to resolve this issue.<br />
<br />
Thanks,<br />

Microsoft Forefront, formerly known as Internet Security and Acceleration Server (ISA Server), is a network router, firewall, antivirus program, VPN server and web cache that runs on Windows servers. It includes identity management and protection systems, and discontinued systems for threat management and network protection, along with protection for Sharepoint and Exchange. The scope of discussions includes forward and reverse proxy, application and service publishing, virtual private networks (VPNs), outbound access rules, SSL certificates and network routing within either a single node or an highly-available array pairing.

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).

Internet Protocol Security (IPsec) is a protocol suite for secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session. IPsec can be used in protecting data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). IPsec is an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite.
