Single IP Failover Pair

[manuadoor]

Hi,

My internet leased line will be terminated on an ASA 5510 which is in Active/Passive Failover. My problem is I have got a /30 address range from ISP.

Total 2 IPs, one IP will be in ISP router.. and only 1 left for me.. I cannot use any extra device between ASA and ISP router.

Regards,

Manu B.

cisconell,

That is correct. There is only one active IP and standby IP. In your case the standby IP is 0.0.0.0

The only problem with that is you cannot monitor the interface.

Failover will work perfectly fine but, Cisco recommends that you have an IP address configured as standby IP address.

Thanks Kureli,

The only problem with that is you cannot monitor the interface. -------which mean when the outiside interface of ASA 1 goes down it will not failover to ASA 2 ?

Or it even dont accept to apply the config monitor interface outside ?

Dear Kureli,

i have the same issues from my ISP i  have only one IP, so the failover will work fine right ?
