Hi to all,
Forgive me if this is the wrong section, but I am just practically clueless where I will place my question.
I am puzzled on an issue which I've just stumbled upon recently. I have this client, a university here in the Philippines and they are having some trouble regarding their website. They have a cisco 1841 router with 12.4(3i) IOS
You see, from their intranet, they can go anywhere from browsing sites all over the internet and of course accessing their own internal servers. The problem is when they are accessing the server, their website over the internet.
They have a 4mbps connection, and they claim it is 4mbps on both the upload and the download. I've looked into their router's running config, yes they have NAT-ed port 80, 81 and 443 of the said server so that users over the internet can browse through their website. I also noticed a QoS Mapping for the server and the protocols required to run it.
This one is for the protocols like dns, http, pop3, shttp, smtp and ssh
bandwidth percent 20
police cir 2000000
and this one's for the server itself
police cir 3000000
Our problem here is that, many users on the internet are complaining that they cannot access the webpage, worse their browser pops up the "Page Cannot be displayed" message. But they can access the webpage on their intranet. I have also checked the CPU and memory utilization, and it is nowhere near 25%.
I have also tried to ping the server's public address for one whole day and fair enough, it generated just about 7% loss. But on that same day, I'm trying to access their website but there are times when I can view their webpage and sometimes I can't. It's just so random...
I don't know where to look. I am not even sure if it is the router's fault, the configuration, the server itself, the number of users, or are they exceeding the 3mbps limit that the router drops exceeding traffic? Please help
