2 ISP and load-balance

[juan-santamaria]

Hi, i have a Pix and 2 ISP, I need to make load-balance. But only use default-route for both ISP. it is not use never exterior protocol. Some advice for solve this situation

[millerv]

The pix will not do load balancing. you need to check

to see if a local director would help

[juan-santamaria]

what type of software/hardware made that. (local director)

i can to made load balance use OSPF or IGRP and asign NAT to each interface, and use static asign for the server and use IP of two ISP for the same server

local director 430 its a cisco product.

Might be easier to implement than doing routing changes

[i.vorontsov]

Local Director is loading balancing for INCOMING connections. For many people needs load balancing for both OUTGOING and INCOMING connections.

The right answer may be this: use BGP with PI addresses. But some customer may use IGRP(EIGRP) beetwen ISP and customer, but this scheme is not real: (ISP-1(IGRP)<-->(IGRP)Customer(IGRP)<-->(IGRP)ISP-2(IGRP)<-->(IGRP)ISP-1). :)

You won't be able to do that natively with a PIX. You would need to implement BGP between the ISP's. Local Director is designed for Load blanacing content not ISP connections.
