Hello and thanks for the help.
I have a client "A" that cannot ping, tracert, or connect to via FTP to their Client "B". The Client "B" has an FTP site up and running which has been tested from Clients "C" through "Z", i.e. a lot of other sites. At Client "A", we try to ping the Client "B", but it times out. Also, a tracert to Client "B" from Client "A" comes up with * * * and dies after about 8 hops. I have talked with the ISP at Client "A" and the ISP techs can perform the Tracert and a ping successfully. Also, the ISP can connect to the Client "B" FTP site successfully. The ISP claims that we are blacklisted from the BLARSBL with a code of 127.1.0.33 & 127.3.0.0. I have other clients with the same blacklist and they can connect to the Client "B" FTP Site.
