I have a 515E running 8.0(3). The PIX is sitting in a colo and I have a bridged DSL circuit running from my office (which is in another building a few kilometers away) to the inside interface of the PIX. This all works fine and dandy, but now I want to turn up a second bridged DSL circuit to double up the bandwidth between the office and the colo.
2 questions -
1) If the PIX does equal cost load balancing, is it per-packet or per-destination (hopefully the former!)
2) Assuming it will, are there any caveats to doing things this way with regards to NATing from 2 inside interfaces to one global, even if I turn of ip verify reverse-path on the two inside interfaces (vlans)?
Here are the config snippets for what I'm trying to do (except the second office circuit doesn't quite exist yet):
ip address x.x.x.x 255.255.255.248
ip address 172.20.15.1 255.255.255.0
ip address 172.20.16.1 255.255.255.0
ip verify reverse-path interface outside
global (outside) 1 interface
nat (outside) 1 192.0.2.0 255.255.255.0
nat (office636) 0 access-list office636_nat0_outbound
nat (office636) 1 192.168.100.0 255.255.255.0
nat (office637) 0 access-list office637_nat0_outbound
nat (office637) 1 192.168.100.0 255.255.255.0
router eigrp 100
network 172.16.0.0 255.240.0.0

Thanks in advance.
