CISCO ASA 5505 double Wan

Hello

I would like to know if it is possible to configure a CISCO ASA 5505 with 2 different WAN :
- WAN 1: SDSL link 2Mb to an ISP
- WAN2:  VDSL link 18Mb to another ISP

WAN2 will be used for internet surf, O365 mailboxes
WAN 1 will be used for a separate IpSEC link to an external site

It is possible to configure the ASA 5505 for this use?

Thank you very much

I don't see why not.

For the SDSL link:

1. Configure it with a security-level 0
2. Give it a name
3. Configure the external IP for that ISP
3. Create a route that points to that ISP for traffic going to the other endpoint's outside interface
4. Configure the IPSec tunnel as normal - crypto map, transform set, ACL, etc.

For the VDSL link:

1. Configure it with a security-level 0
2. Name it 'outside'
3. Configure the external IP
4. Point route 0.0.0.0 0.0.0.0 to that ISP's gateway.

That should do it, I think.

THank you very much

But how do you tell to the ASA that O365 mail traffic and regular Web surfing will go to the VDSL?  

It there something special to order for the double Wan option (special licensing of the ASA) or is the option included standard in the product?

THank you again

I guess that for 2 WAN/ISP and IsPEC tunnel I need the "CISCO ASA 5505 SECURITY PLUS" licence
It that OK ?
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

Gadsad,

You shouldn't need the Security Plus license.  You're not doing any kind of failover and IPSec functionality is included in the base license, so that should be okay, too.

Regarding the traffic, you  don't really need to specify what traffic goes where other than the traffic specifically destined for the other private network via the IPSec tunnel.  Everything else will go out to the internet.

Are you comfortable setting this up?  If not, we can set up a Gig through Experts Exchange where I can help you set it up.

I am looking for IPSec for also for dual WAN (2 different ISP)

Are you sure dual WAN is included in the base licence?
Regarding traffic I want IPSec tunel traffic go through Wan1 and regular Internet traffic (web surf, download, ect...) go through Wan2

THank you
