We have a VAP that is configured to tunnel to VLAN122 on our controller. Users can authenticate and are assigned the authenticated role (with allow all).
While connected to this VAP, users are able to access external and WAN resources without issue. If they attempt to browse local fileservers (different vlan) they are able to browse the directory but it is sluggish. If the user opens a small 250 kb pdf file it takes about 1-2 minutes and often causes the application to hang.
I mapped a port on the controller as an access port on vlan122 and have no problems accessing the server or files.
I reviewed the datapath session table for the specific user (during troubleshooting) and do not see any Deny flags. I have also verified that this is not RF related. I have looked at MTU size and reviewed the configuration repeatedly but cannot find any errors.
