source quench icmp and advice

[cc <cc () belfordhk com>]

Hi,

I've been getting quite a few of these icmp packets
from a particular host, and I'm a little perturbed
about this.

I've read about what a source quench packet does
so I'm worried whether or not my routing system
is screwed up or if the packet source IP is
DoS'ing me.

Also, I'd like to get some advice.  On what
system should snort be used?   I'm currently
testing it on my company's firewall.  Is that
the right place?  I figured that since that's
the access point from the Net to the LAN,
it would be a right place to check what
items of interest are hitting my firewall.

Thanks
