Perhaps MRTG and getif use another source port number and you
have a firewall somewhere inbetween (maybe on the mrtg host) that
does allow udp161<->udp161 and doesn't allow udp<random> <->udp161?

You could try tcpdump to see what's going on.
Much of what looks like rudeness in hacker circles is not intended to give
offence. Rather, it's the product of the direct, cut-through-the-bullshit
communications style that is natural to people who are more concerned about
solving problems than making others feel warm and fuzzy.
