Hi everyone, Can anyone help me please.
I have a following setup.
Cisco WLC 2504
SSID- Guest
Interface name – guest Interface ip address – 10.10.10.2/24
Interface name - management Interface ip address 10.1.1.2/24
WLC2504’s port 1 is connected to port 24 of cisco 3750.
On Cisco 3750 I have a following config.
Int vlan 2 - ip address 10.1.1.1 /24
Ports 1 to 20 on cisco switch are set to access vlan 2.
Int vlan 10 – ip address 10.10.10.1/24
Int g22 - no switchport - ip address 192.168.0.2/24
Int g24 is set as trunk link to port 1 of WLC and it carries vlans 2 and 10.
Ip route 0.0.0.0 0.0.0.0 192.168.0.1
For internet connection clients have purchased virgin media broadband and I have been supplied with a virgin media superhub (unfortunately due to firmware issue I am not able to convert this superhub to modem only mode. I will check with tech support what my options are). But as it stands this superhub has lan IP of 192.168.0.1 . Basically this superhub has 4 port switch built in. so I have connected one of the port to int g22 of cisco 3750.
If I connect a laptop to one of this ports on superhub I can get onto internet without any problem. If I connect a Cisco switch to the lan port I can ping google, bbc.co.uk etc if provide the dns server settings on the switch. So Cisco switch is able to connect to outside world via this superhub.
As I have a dhcp scope configured on cisco switch for vlan 2 and vlan 10 ranges, if I connect my laptop into one of the ports on cisco switch, I am getting IP address in 10.1.1.0 range from DHCP server.
Now my problem is… From my laptop I can ping 192.168.0.2 (int g22 ip address) on cisco switch. I can also ping other SVI ip addresses but I simply can not ping 192.168.0.1 (ip address of lan interface of superhub).
I just can’t work out why I can’t reach beyond Cisco Switch.
My access points do receive IP address from 10.1.1.0 range when connected to ports 1 to 20 on Cisco switch. My wireless devices are able to connect to ssid guest without any problem and wireless clients receive ip address from data vlan 10 ( 10.10.10.0 range) .. But these client can’t ping wireless controller IP addresses 10.10.10.2 or 10.1.1.2 . At times I have been able to ping 10.1.1.2 but more often then not it doesn’t work.. however before I try and diagnose this wireless issue I am stuck with Lan connection problem described above.
I hope all that makes sense and someone is able to suggest some sort of solution.
Thanks. Regards.
Solved! Go to Solution.

As said please add a static route between the two subnet with the default gateway address as 192.168.0.2
