I have found that my ipchains firewall is blocking SecureRemote clients. I can open the required ports I need to in order to let it through, but I am a bit confused as to what to do about IP Protocol 50. I guess I am wondering, how do I allow it through an ipchains firewall?
After using a packet sniffer, I can see this traffic (PROTO050), however it does not seem to use a specific port. In fact both the source and destinations do not include a port number. I don't quite understand how it exits the computer via TCP/IP without using a port??? I would realy appreciate help as I just don't understand this.
