Load Balancing Inbound Traffic Two ISP

Hello everyboy,

I have the following topology,

 

DMZ Network -> ASA (Active/Standby) -> Two Routers Cisco 2951 -> Two ISP

 

Mi question if there  is a way to truly get load balancing for the inbound traffic to one server, so the server can respond request coming from both ISP.

Thanks in advance.

Hello

I think ASA will be unable to do load balance for incoming traffic , it unable to do PBR . You can do only as below , let say ISP 1 X.X.X.X and ISP2 is y.y.y.y and your inside server is 192.168.2.110

 

static (inside,ISP1) X.X.X.X 192.168.2.110 netmask 255.255.255.255
static (inside,ISP2) y.y.y.y 192.168.2.110 netmask 255.255.255.255

or 

static (inside,ISP1) tcp X.X.X.X 443 192.168.2.110 443  netmask 255.255.255.255 
static (inside,ISP2) tcp y.y.y.y 443 192.168.2.110 443 netmask 255.255.255.255

 

For professional load balancing solution , you have to use F5 .

F5 devices which can be used as " GTM 2000S for DNS smart solution load balancer , and ADC 4000s for load balance between your DMZ servers applications ". 

thanks

please rate all useful information

Hello,

I have two routers each one to connect to every ISP, so the NAT shoul be done in the routers, using PBR you can get load balancing sending some server by ISP A, and other servers sending by ISP B. What I want get is that every server can repond requests coming from both ISP.

 

Thanks for the help.
