Remote guest canot go to the Internet

[ngutri]

Controllers: 7200s, AP-105, AOS 6.5

I have a remote site with two Wi-Fi networks: Employee is bridge, and guest is tunnel.  All APs at site are terminated at the HQ controller.  Recently switch upgrade at this site causes guest not working.  Nothing change at the controller.   Althought I can see guests connect, getting correct IP addresses and DNSs but when user open web browser or any apps, nothing work.  I can even see the guest users on firewall logs that show traffic is passing. 

Any ideas or suggestions?  I cannot be at the site, and no IP personnel available at site, just typical user.  Note that employee Wi-Fi is working normal.

Regards,

Has there been any routing changes? Can you confirm the firewall has a correct route back to the guest subnet?

Hi,

No routing change.  Guest is L-2 user-> AP -> controller -> FW, and FW is the gateway.  FW access tracker shows correct guest user IP, and guest traffic is passing. 

Thanks for looking.

Type "show datapath session table <ip address of guest>" to see what traffic is being sent back and forth.

Sounds odd, I assume your User Roles are as per they were before and working? If you run a packet capture on the client do you see the internet traffic returning at all?

[ngutri]

does this look like it working?

I think you need to do more troubleshooting.  There is nothing that I can see from this client's traffic.  What is the default gateway for this client?

[ngutri]

Gateway is 10.18.0.1.

[cjoseph]

and what is that device?
