There may be some SNMP blocking going on to protect from SNMP
vulnerabilities uncovered by OUSPG in Feb, 2002 which affected several
vendors:

Subject: ISPs block SNMP?
ISPers,
I've been playing with snmpwalk a bit the last couple days, but
was
starting to think it wasn't compatible with Cisco routers. Turns out
that
it's being blocked by an ISP somewhere out there along the way, as I
tried
to get to a couple different devices. Is it standard operating
procedure
for ISPs to block SNMP? Wasn't an access-list on any of my devices
causing
the problem. Just wondering...
Thanks,
Chuck Church
