I am Network Administrator in a small organization.I manage few number of Routers,Switches,VPN firewalls. Management is done through web based management(through browser),through telnet,or through SSH. One new Cisco 1841 ADSL router terminates incoming internet connection from a service provider, which has connection to VPN firewall and LAN switch (Cisco 2950 series). I was managing through web based management(i.e from browser, something like http://192.168.1.5) One fine day, last week, when I entered this address, it got redirected to Cisco 2950 switch and when I refresh the page I get Document Contains No Data.If I refresh the page again at another instance, I get the initial page of Original Device's (Cisco 1841 Router) I dont know what causes this mess!! Could anyone guess what causes this toggle??
