Also beware of MTU "black holes" where a 9k MTU host tries to talk to a 1500 byte host and large packets just get dropped leading to confusing "small emails get through but big ones don't" "I can view googles home page, but not the search results" "I can ssh, and ping, but I can't scp" style issues.
