ipchains log

Hi,

I'm just setting up a masquerading firewall and I'm getting some log messages
I don't completely understand like the follwing:

pluto kernel: Packet log: input DENY eth0 PROTO=1 210.86.82.93:3 xx.xx.xx.xx:3
.....

I've found out that that's an ICMP packet, with type Desination Unreadable and
code Port Unreachable, but I'm not sure what this means.  Is it important, and
is there any way of stopping it?

Thanks

Bec
