Can Cisco ASA-5505 support 2 simultaneous Internet Provders

Posted on 2013-10-29

Have a client that has a Cisco ASA-5505 and a single internet provider (which they would like to dump in November).

The question is can I get a second internet provider, and simultaneously connect them to the ASA-5505 as a second WAN connection, my guess is no, but I'm not a Cisco expert so I thought I would ask.

You mean as a backup connection?
Should be possible if you have a Security Plus license, you could then create a backup connection using sla's.

Should be something like:

asa(config)# interface ethernet 0/0
asa(config-if)# switchport access vlan 1
asa(config-if)# no shutdown

asa(config)# interface ethernet 0/1
asa(config-if)# switchport access vlan 2
asa(config-if)# no shutdown

asa(config)# interface ethernet 0/2
asa(config-if)# switchport access vlan 3
asa(config-if)# no shutdown

asa(config)#  interface vlan 1
asa(config-if)#  ip address
asa(config-if)#  nameif outside
asa(config-if)#  no shutdown

asa(config)#  interface vlan 2
asa(config-if)#  ip address
asa(config-if)#  nameif backup
asa(config-if)#  no shutdown

asa(config)#  interface vlan 3
asa(config-if)#  ip address
asa(config-if)#  nameif inside
asa(config-if)#  no shutdown

asa(config)# nat (inside) 1
asa(config)# global (outside) 1 interface
asa(config)# global (backup) 1 interface

asa(config)#  route outside 1 track 1
asa(config)#  route backup 254

asa(config)# sla monitor 100
asa(config)# type echo protocol ipIcmpEcho interface outside
asa(config)# num-packets 4
asa(config)# frequency 10
asa(config)# sla monitor schedule 1 life forever start-time now
asa(config)# track 1 rtr 100 reachability

It is totally possible. I'm doing it right now with a customers 5505.
