Is it possible that ConfigServer Security & Firewall blocks communication of WHMCS with registrar?

Hi all, we installed ConfigServer Security & Firewall yesterday and last night I noticed that I cannot update (nor register) domains with registrar through WHMCS. I have contacted the registrar and they confirmed there is no problem at their end. Does anyone know what setting might be wrong in CSF that could possibly block registrar communication through WHMCS? Thanks

  You'll prob. want to check with your registrar and see what port you use to communicate with them. Then make sure that port is in TCP_OUT (assuming it's TCP) or put in a specific entry into csf.allow. You can grep through /var/log/messages and search for TCP_OUT or UDP_OUT to find any blocked outbound connections.

  Thank you for the pointers. Tcp port added and the module started to work. :)
