The only other way that I know of to avoid crashing the router, and getting a useful "sniff" of the WAN traffic, is to use a V.35 protocol analyzer, such as the HP Internet Advisor. This is a pricey unit, but if you do this stuff regularly (as my coworkers and I do), it is the easiest, and most presentable way to do this. Note: There is a short disruption of service while inserting and removing the V.35 Y-cable used to do this.
Internet Advisor generates some very management-friendly reports, used to present findings to people of a slightly more non-technical background. It also has many VERY powerful features (think: SnifferPro-like GUI). I am sure there are other very similiar products out in the field, I am only explaining what I have used. At the present time, this is only the HP Internet Advisor.
