VLAN and Routing

BBDOmexico — Mon, 14 Jun 2010 21:25:43 GMT

Hi Guys,

I have an issue.

I have a PAN-500, I am using 3 interfaces: et1/4 is L3-Untrust, et1/3 is L3-Trust and et1/2 is L3-Trust.

ET1/4 has the public IP.

ET1/3 = 192.168.0.254/22

ET1/2 has 8 sub interfaces, each subinterface has its own IP addressing and belongs to differnet VLANs.

et1/2.1 192.168.9.0/26 TAG 30

et1/2.2 192.168.9.64/26 TAG 31

et1/2.3 192.168.4.0/28 TAG 40

et1/2.4 192.168.4.16/28 TAG 41

et1/2.5 192.168.5.0/27 TAG 50

et1/2.6 192.168.6.0/27 TAG 60

et1/2.7 192.168.7.0/26 TAG 70

et1/2.8 192.168.8.0/28 TAG 80

The Virtual Router is as follows:

default	0.0.0.0/0		ip	200.78.237.126	none	1
wifiomd	10.0.1.0/24		ip	192.168.0.30	none	1
wifibbdo	10.0.2.0/24		ip	192.168.0.30	none	1
wifisistemas	10.0.0.0/24		ip	192.168.0.51	none	1
vpnaccess	172.16.0.0/24	tunnel	none		none	none

finanzas	192.168.6.0/27	ethernet1/2.60	none		none	none
proximity	192.168.7.0/26	ethernet1/2.70	none		none	none
produccion	192.168.4.16/28	ethernet1/2.41	none		none	none
servers	192.168.0.0/22	ethernet1/3	none		none	none

The problem here is that users on VLANs are unable to communicate with the network 192.168.0.0/22.

What can I do in order to solve this issue.

Thanks in advance.

Hello,

both interfaces ethernet 2 and ethernet 3 are in the same zone and we do allow intra zone traffic. So the traffic should be allowed UNLESS you have a deny all rule in your policies. If you have the deny all rule then that includes intra zone traffic.

Try creating a Trust to Trust rule to allow the traffic and move it to the top of your rule set. If your traffic starts flowing then this was probably the issue.

I have created a Trust to Trust rule, allowing all traffic. I have just moved to the top, but I am unable to communicate from VLAN users to Network 192.168.0.0/22, and viceversa.

Is anything else, that I should do.

Thanks in advance.

Are you sure that the traffic is being routed to the Paloalto device?

Are there session in the Paloalto device when try to communicate to users in the 192.168.0.0/22 subnet?

There are numerous issues that could cause this, at this point it will probably be easier to call into support to aid you in troubleshooting this.

thank you,

Hello Stephen,

The traffic is being routed to the PAN-500.

In fact, PAN-500 is the default gateway for all the VALNs and the Network 192.168.0.0/22.

I am able to see the traffic from Trust to Untrust, and from Trust to Trust.

Users in VLANs can access Internet.

Thanks in advance.

Do you have sessions where the destination address is with this subnet: 192.168.0.0/.22?

If so are the sessions allowed?

Is the device that you are trying to reach in 192.168.0.0/22 network able to ping the interface on the paloalto device?

Can you call into support in order that we can take a look?
