We are currently running ASA9 at a location with redundant ip connectivity. We'd love to configure
ip sla so that internet access survives a single carrier outage. I'm aware of the ip sla commands, however when I've tried to prepopulate the required NAT rules, the addition of the second rule will overwrite the first. Here is an example:
object network NYHQ_GUESTWIRELESS_10.110.6.0_24 nat (NYHQ-GUESTWIRELESS,NYHQ-OUTSIDE_FIOS) dynamic interface
When I attempt to add an additional nat rule, perhaps
nat (NYHQ-GUESTWIRELESS,NYHQ-OUTSIDE_COGENT) dynamic interface
The new rule overwrites the preexisting rule, as so:
object network NYHQ_GUESTWIRELESS_10.110.6.0_24 nat (NYHQ-GUESTWIRELESS,NYHQ-OUTSIDE_COGENT) dynamic interface
Is there any way that I can have both of these rules in place so that NAT can cooperate with our SLA rules to ensure that regardless of which provider is used, NAT still works properly?
