ASA 5510 vlan cannot reach wan

Mediadeshaies — Mon, 11 Mar 2019 23:12:35 GMT

Hi everyone,

i'm setting up vlan and inter-vlan routing in my lab. My vlan work well (routing between them and dhcp relay) on the LAN side of the ASA but they cannot reach internet trough the ASA.

I read a lot about this issue and tried different configurations but i can't solve it...

Exemple of what i read and tried

Here my ASA settings :

Note : I know that the physical interface musn't have an @ip but my present network needs one to work. I'll fix this during my next tests.

ASA 5510 vlan cannot reach wan

Jennifer Halim — Mon, 28 May 2012 07:56:57 GMT

which particular vlan can't access the Internet?

you would need to have a NAT statement for those vlans so it gets PATed to the WAN_FREE interface IP Address (public IP) to be able to reach the internet.

So far, only the following interface will have access to the internet:

LAN and vlan_postes:

nat (LAN) 1 0.0.0.0 0.0.0.0

nat (vlan_postes) 1 192.168.31.0 255.255.255.0

nat (vlan_postes) 1 0.0.0.0 0.0.0.0

ASA 5510 vlan cannot reach wan

Mediadeshaies — Mon, 28 May 2012 08:19:45 GMT

Hello Jennifer Halim,

Actually, only vlan_postes needs to access the internet. So i set the NAT but it doesn't work.

I don't understand very well what you mean by

 so it gets PATed to the WAN_FREE interface IP Address (public IP) to be able to reach the internet.

Do i have to set something more than

nat (LAN) 1 0.0.0.0 0.0.0.0

nat (vlan_postes) 1 192.168.31.0 255.255.255.0

nat (vlan_postes) 1 0.0.0.0 0.0.0.0

Or may my ACL be the problem ?

ASA 5510 vlan cannot reach wan

Jennifer Halim — Mon, 28 May 2012 09:29:25 GMT

you have not applied the global-policy yet:

service-policy global-policy global

Then try to ping 4.2.2.2 and see if you get a reply.

ASA 5510 vlan cannot reach wan

Mediadeshaies — Mon, 28 May 2012 12:12:23 GMT

Hello Jennifer Halim,

i tried to apply what you said, it displayed this message:

ERROR: Class global-class1 has 'priority' set without 'priority-queue' in any interface

So i tried this :

CISCOASA/pri/act(config)# policy-map global-policy

CISCOASA/pri/act(config)# no class global-cass1

And it displayed :

ERROR: % class-map global-class1 is being used

My knowledge about ASA and policy in general is really poor. So i'm a bit lost

Do you have any idea?

Thank you

ASA 5510 vlan cannot reach wan

Jennifer Halim — Mon, 28 May 2012 12:18:54 GMT

Just create a new policy and apply it as follows:

policy-map global_policy

class global-class

inspect dns migrated_dns_map_1

inspect esmtp

inspect ftp

inspect h323 h225

inspect h323 ras

inspect icmp

inspect netbios

inspect pptp

inspect rsh

inspect rtsp

inspect sip

inspect skinny

inspect sqlnet

inspect sunrpc

inspect tftp

inspect xdmcp

service-policy global_policy global

Re: ASA 5510 vlan cannot reach wan

Mediadeshaies — Tue, 29 May 2012 09:13:49 GMT

Hello Jennifer Halim,

here the configuration after i tried your solution. New lines appeared but ping still not working (4.2.2.2 or 8.8.8.8).

Note : i removed the @IP from the physical interface ethernet 0/1 before to do the test
