A few customers complaining ... Sunrise filtering ICMP ? ...
You should think before filtering all this. Too much problems because of this.
Right. ermm...
What about other kind of ICMP ? do they filter any ICMP packet or just ICMP echo request/reply ? If they filter any ICMP packet they just break the rules, what about host unreachable ? MTU exceeded ? and all other kind of ICMP which are ESSENTIAL to run the Internet correctly !?!?
IMHO, this is not acceptable.
