I have a customer that is reporting the above issue from a single site
Wired clients at this site can RDP and SSH
Clients at other sites, supported by the same WLC, can connect via RDP & SSH via WiFi
There are no access lists on the WLC
Is this far more likely to be a LAN/WAN/FW issue
Is there any debug I can run on the WLC that might identify the issue or is this the realm of sniffing the LAN/monitoring the Firewall
the clients cannot start RDP or SSH? is the application installed on these clients?
is the connection refused? then check if the subnet used on this site is allowed at the destination.
if other do basic steps like
- ping default gateway from client
- ping remote gateway from client
- ping ssh/rrdp destination
- traceroute to destination
is the AP involved in local mode (date delivered to lan centrally by WLC)?
or flexconnect mode (data delivered by AP to local vlan)?
in second case, then the subnet mask retrieved from the dhcp scope may not be correct, so it cannot reach the central site through the gateway
It turns out the fault description is not entirely accurate
The issue is not just for 10.108.156.xx addresses but affects the whole subnet due to a Cisco bug CSCvb78700 affecting the 4500 core switch
