a router from dropping pings...
for instance I cant ping my machine from work...and my buddies cant. I think my router is dropping any ping requests. How can I allow for ping requests?

yeah you can forward it to whatever computer on your network is to be pinged
What does pinging mean?
When you ping someone you send them ICMP (Internet Control Message Protocol) echo request packetQuote:

In repsonse the host you have sent the echo request packet to should reply with none other than an echo reply ICMP packet.
The ping utility generates output simillar to this:
The purpose of the pinging is to determine network connectivity with another host. If the echo request doesn't get a reply, it means the host cannot be reached.Code:PING 192.168.0.3 (192.168.0.3): 56 data bytes
64 bytes from 192.168.0.3: icmp_seq=0 ttl=128 time=0.3 ms
64 bytes from 192.168.0.3: icmp_seq=1 ttl=128 time=0.3 ms
64 bytes from 192.168.0.3: icmp_seq=2 ttl=128 time=0.3 ms
64 bytes from 192.168.0.3: icmp_seq=3 ttl=128 time=0.3 ms
--- 192.168.0.3 ping statistics ---
4 packets transmitted, 4 packets received, 0% packet loss
round-trip min/avg/max = 0.3/0.3/0.3 ms
ICMP doesn't use ports. You just need to accept/forward ICMP packets.Quote:

Whether or not they send you a reply is another story. Many hosts block ICMP packets from the internet becuase malicous users flood them with pings from spoofed addresses.
