Checkout BGP. Two ISP's, one router (with BGP configured), one firewall, one external (public) network address. Pete Papadopoulos [email protected] -----Original Message----- From: Srinivasa Rao Bandaru [mailto:[email protected]] Sent: Tuesday, March 19, 2002 9:19 AM To: [email protected] Subject: [FW-1] Multiple ISPs from firewall.... Hi, I am just planning for resilience for the internet mail traffic. As part of this we are planning to have another internet connection from another ISP, So that if one internet connection goes down, the other internet connection wud be there for the mail traffic. I am using CP4.1-SP5 on Nokia IPSO-3.4. But I would like to know about the following issues: What happens to the NAT translations on the firewall? They are hard coded with 1st internet valid addresses in the firewall implied NAT rules. Suppose if the 1st internet connection goes down, the packets would go through the 2nd internet connection as 1st internet valid addresses according to NAT rules, But the reply would still tries to come through 1st internet link obviously and fail..... How can firewall know about the status of two internet links and route accordingly? How do I configure load sharing? I hope I am clear here. Please let me know the various solutions for this. Thanks a lot in advance. -Srinivas B. This message is confidential and may also be legally privileged. If you are not the intended recipient, please notify us immediately.
