SNMP scan for certs

[snowden]

month ago our isp update the system .

i can ping all other modems 10.X.X.X range
but can´t snmp anymore. other modems.

did isp install like a firewall? all ports to 10.X blocked.
how can read isp then our modems with snmp?.
because they have acces to CMTS?.

on forceware i see incoming snmp scans from isp.

thx in advance

welcome in the club babe
i cant even ping modems near me
if is firewall issue then you can try this trick _http://www.forocable.com/foro/threads/32967-Scan-snmp-etc-open-subnet-metodo2
however yours isp could use vlan managment to isolate everything
