Re: Traffic sharing b/w two ISP'S

Hi ,

1 .NAT mail server or Exchange server local IP with ISP B Public IP

2. NAT Your LAN Proxy server / ISA server Local IP with ISAP A Public IP

3 . Do a route -map on the Gwateway router to force ISP A IP's go through ISP A and ISP B IP's o go through ISP B .

Another way will be doing one ACL to match http traffic and another ACL to match smtp traffic and do a PAT (NAT overload ) making this accesss-list as souce list with ISP A and B

I hope this helps

Regards,

Haris
