Looks like a routing issue.

Is ping allowed via firewall ?

 

Can you please a Draft.. how are these connected then we can try to find-out the root cause.

from fw clavister  : i can ping 172.16.81.1 ( gatway  vlan 7)  for user  but i can't ping 172.16.81.2: address ip vlan 7 ( in wlc )

 

switch 9200 conncted router  and router conncted to fw 

 

 

 

 

connect laptop with LAN cable on switch with vlan 7 and check if you can access internet or can ping the firewall or not ?

Vlan 1 is always untagged so that is your problem. You can’t make vlan 7 native (untagged) and also have vlan 1 work.

Try tagging vlan 7
interface GigabitEthernet1/0/13
switchport trunk native vlan 1
switchport trunk allowed vlan 1,7
switchport mode trunk

the problem is resolved ...not yet !!

 

 

You should not open a new thread on the same thing.  You need to understand how vlans are tagged and then look over your design.  Vlan 1 from majority of all manufactures will not look at the tagging.  What this means is that vlan 1 is untagged, if you try to tag this vlan on other devices, the switches will ignore it as it is looking for untagged vlans.  So redo your vlans because it is not right.
