[AusNOG] Bigpond contact?

[Shaun Ewing]

Hi All,

Are there any Bigpond/Telstra staff lurking that might be able to help with
an issue?

Servers in our 113.20.0.0/20 block are unable to connect to mail.bigpond.com
(and potentially other hosts within AS1221), whereas servers in our
117.55.224.0/20 and 203.88.112.0/20 blocks have no issues connecting.

113.0.0.0/8 is relatively new (May 2008), so I suspect this may be related
to outdated bogon filters.

Failed example from 113.20.4.209:

# host bigpond.com
bigpond.com has address 144.135.18.32
bigpond.com mail is handled by 10 extmail.bigpond.com.

# telnet extmail.bigpond.com 25
Trying 61.9.189.122...
(timeout)

Working example from 117.55.224.225:

# host bigpond.com
bigpond.com has address 144.135.18.32
bigpond.com mail is handled by 10 extmail.bigpond.com.

# telnet extmail.bigpond.com 25
Trying 61.9.189.122...
Connected to extmail.bigpond.com (61.9.189.122).
Escape character is '^]'.

A traceroute from 113.20.4.209 (failed server) does not get past
203.50.19.182:

hitting what's probably a firewall:

Any help that anyone might be able to provide would be appreciated.
