[swinog] IP network not reachable from switzerland - 69.162.65.122, but from outside, eg belarus/brasil

hello all,


we can NOT reach the upper IP from:

- swisscom mobile
- cablecom.biz
- cablecom home
- swissix


but:
from our brasilian firewall I can ping host and reach smtp / http
sockets - also from a belarus provider.

and also from a testsite, hosted in germany / hetzner, the IP is
reachable.


but effectively from not any switzerland ISP reachable :-(

sad is, that reverse.lstn.net is dropping ICMP packets / traceroutes
not possible in any case

so host 69.162.65.122 is only answering to ICMP echo requests,
and listens to tcp25 and tcp80

could you be so kind and check, if you can connect to this host, and
tell me, via which ISP / peering ?

thanks in advance

stephan

not particularly true...

We have the prefix in our table and are advertising it to Hetzner, I 
suppose. Check our LG in case: http://www.init7.net/looking-glass/index.php
