Firewall Ports for ERP

Hi Friends,

I just installed ERP6 with EHP7 on SuSE Linux Enterprise Server 11 SP2(SLES), but I found that I could not connect the ERP from SAPGUI unless I disable the firewall of SLES. I have opened tcp ports 3200 3300 3600 3601 on the firewall, could you please tell me if any ports needed ?

Thanks & Regards
