NAT on failover
Hi GC, Thanks for the quick reply. I am currently using route-maps for the NAT but my impression is that it will only perform the NAT when the traffic type matches the ACL. For something like SMTP, wouldn't the translation need to be in place first even before it receives the first matching... -
NAT on failover
Hi All, Any idea on how to do a static port NAT on failover? E.g NAT 1.1.1.1 port 25 (IP on BRI interface) to 2.2.2.2 port 25 (one of the IP from primary interface IP range) ONLY when primary link fails and BRI comes up? Need to do this to allow smtp connections during line failover... -
Network Design Problem
Hi Andy, You're right. It's not an enterprise setup. Unfortunately I'm forced to work within the constraints provided by my client. As they're not prepared for 2 routers or 2 firewalls, I might just need to NAT the traffic multiple times. Through the router and then through the firewall again... -
Network Design Problem

Network Design Problem
Hi Andy, Although your HSRP solution provides an interesting solution to my problem but I strongly doubt that my client will fork out the extra cash for an extra router. As for the DNS part, I was going to associate the domain name with 2 MX records with different preference values. Thanks anyway -
Network Design Problem
Hi Andy, Thanks for the prompt reply. I've found out however that ISA would not support 2 external networks and therefore HSRP would not work. I think I'll need to look for another way around this. -
Network Design Problem
Hi All, I will be implementing a network using a Cisco 1721 router using ADSL as it's main link and ISDN as a DDR solution for redudancy. The problem is that an email server needs to be located in the router's LAN segment. Worst yet, a microsoft ISA firewall will sit between the router and the...
