Trouble with Proxy configure setting in CentOS 5

Hi guys:

I am trying to install a router on my CentOS 5 box, while i have properly configured IP address, Subnet, Default GW and DNS, I am at the point of trying to set up the Proxy.

I need some help with setting up my proxy

I have added a line: "proxy=http:ip_address:8080/" to the file of "/etc/yum.conf"
The Proxy server here does not require any username nor password

however I still cannot ping any website, while I tried to ping (
it returns the following message:

From icmp_seq=25 Packet filtered
From icmp_seq=34 Packet filtered
From icmp_seq=89 Packet filtered
From icmp_seq=129 Packet filtered
From icmp_seq=143 Packet filtered
From icmp_seq=188 Packet filtered
From icmp_seq=201 Packet filtered
From icmp_seq=237 Packet filtered
From icmp_seq=245 Packet filtered
From icmp_seq=258 Packet filtered
From icmp_seq=265 Packet filtered
From icmp_seq=285 Packet filtered
From icmp_seq=329 Packet filtered
From icmp_seq=330 Packet filtered


and then it gives an 100% packet loss message. . .

Can any one please help me? Greatly appreciated!!

Hi, welcome to LQ!

There's a // missing after the http: ...
and having a proxy doesn't necessarily mean that pings are
permitted - give us more detail on your network layout,
is there iptables installed on the proxy?
