I am having a problem with accessing one of the websites on a Cisco network. We have a Cisco 3750X with an ASA5510 in front of it, and multiple VLANs on the network.
The particular website I am trying to access does not work on VLAN113 but works on other VLANs like 130 and 88, for example. All these VLANs share the same physical gateway, which is the ASA and all have the same public IP. There is no URL filtering in place and the only thing I can see that's different, is the DNS. The VLAN 130 and 88 use OpenDNS whereas the 113 uses local DNS server. I have tried changing the DNS to use Google and OpenDNS but nothing makes any different. Flushing DNS cache and deleting temp files makes no difference.
Thanks in advance.
