Hi, I've successfully installed HylaFAX on a SuSE10.1 OSS. I found out that the HylaFAX protocol is much like the FTP protocol. It can work in active and passive mode. The HylaFAX server is behind a Firewall and, I successfully set the passive mode using the ip_conntrack_ftp and ip_nat_ftp modules using port TCP/4559. The HylaFAX server is supposed to be able to receive incoming connections from anywhere in the world from both Windows and Linux Clients. Here is my problem: There are several Windows Clients for HylaFAX but, I found none for Linux. Does anyone knows of a Linux client that supports passive mode? PS: I know that using active mode would be a workaround but, some of those connections are to be made from a UMTS/WCDMA/GPRS connection and, almost all of my local Mobile ISP's have firewalls blocking all incoming connections...
