Hi Sheik, ASA doesn't support

Hi Sheik,

 

ASA doesn't support load balancing or splitting the traffic over two different WAN links. You can make one primary and other as a backup.

HI Sheik,Yes you can do this

HI Sheik,

Yes you can do this.

In your case since all your servers will be connected through leased line and internet through adsl link, you can terminate both links on firewall's two interfaces. All traffic from your all vlans to servers will be routed via leased line (you will need to configure static routes for all servers' range  via leased line and a default route for internet via adsl link. You can control internet access for all vlans through access-list on firewall.

Hi Karthi  Are you sure ??

Hi Karthi 

 

Are you sure ?? becaz customer needed LAN internet packets going to ADSL .

Servers and other vlan traffic going to Leased line Connection .

 

Pls Make sure whether this scenario what  i will do ??If ASA will not do what we can do this customer requirement ?

 

 

Hi Sheik, As per my knowledge

Hi Sheik,

 

As per my knowledge through ASA you cannot achieve it.

  • Through ASA you cannot do policy based routing.
  • Even though you can have two default routes enabled one can be on active and other can be on standby.

This is not possible with your present topology.

Hi Karthik, I had read a

Hi Karthik,

 

I had read a cisco document as below, it stated 9.0 support PBRi:-

http://www.cisco.com/c/en/us/td/docs/security/asa/asa90/configuration/guide/asa_90_cli_config/ha_cluster.html#pgfId-1943033

 

Do you have any idea whether the cisco guide is correct as there is no sample configuration can be refer.

 

Thanks.

Hi, I get through the command

Hi,

 

I get through the command refernce of cisco asa 9.x version.

http://www.cisco.com/c/en/us/td/docs/security/asa/asa-command-reference/I-R/cmdref2.pdf
 
There is a route-map option with ip-next hop feature which can give you the desired result. You can give a try because i do not have any lab option for cisco asa 9.x version OS to test and confirm you.
 
You can try it out.

Also you need to have the

Also you need to have the dynamic routing in place if you want to use route-maps in ASA..... either OSPF or BGP. BGP is available in recent IOS versions..... but you need to have the ISP routers also should support the dynamic routing protocols..... in your case ADSL modem will not do as such i guess.... We can try to tweak something to work.... but not sure or guarantee about this.....

Hi Karthi and others

Pls ASAP

 

Hi Sheik,Can you confirm me

Hi Sheik,

Can you confirm me if your both links (Leased and ADSL) are terminated on firewall?  Are all the traffic going through leased line are private IPs or unspecified? Have you got any public IP pool with both links?

Also can you share me configuration of firewall so that I can suggest you a possible solution to achieve what you want to.Also share me the details of each vlan's IP details.

Hi Rahul its existing setup

Hi Rahul 

its existing setup ,but i will purchase a new 5512 firewall with IPS .they have 2 isp's...

Leased line already configured the firewall .now they taken a ADSL line for internet browsing .

Leased line only for Servers and other vlans.

ADSL Line Only browsing purpose can we configure to  Local Users ...

 

I didn't started the work .Just asking a doubt .whether it is possible or not?? but when i contact one supplier they says is possible .

Please confirm the ASA 5515-X

Please confirm the ASA 5515-X can support Two Internet Lines routing to two different Vlans (Server, Client).
