I want to configure two different ISP to my Cisco ASA 5510 (on two different interfaces).
now, i want some IP, to route defaul traffic to internet via ISP01.
Some other internal IP to route default traffic via ISP02.
So, is this possible?
also, i want to track connectivity on ISP01, if it fails, all the traffic to be routed via ISP02.
Load sharing (part of the traffic on ISP02 link) - no.
Backup ISP link - yes.
You can use static route with object tracking to detect ISP01 failure and re-route outgoing traffic to ISP02
Hey Las ,
you can try this by disributing the load :
route ISP1 220.127.116.11 18.104.22.168
route ISP2 0.0.0.0 22.214.171.124
Hope this helps you.
Thanks & Regards
With this your half internet traffic will go through ISP 1 and half will go through ISP 2.
till 126 subnet the traffic will take ISP 1 as gateway
And For the remaining , traffic will take ISP 2 as gateway.
Thanks & Regards
To effectively use 2 ISP links on an ASA you would need to be running 8.4(x) software or higher.
This would enable you to use NAT to select what ISP link each LAN network uses. Though with this kind of NAT setup the NAT configuration becomes more complicated to manage. I am also not sure if this setup would be able to reach to ISP links going down as with the NAT configuration we are specifically overriding the routing table and using the NAT to decide the interface through which the traffic goes.
So the setups you can do are atleast
Suppose i want to use for failover ISP02. How i've to configure the NAT rules?
Which method you are suggesting as last and better option?
For all of you.
What about VPN??? does it work simultaniosly with both Real IP of ISP?
