My firewall is dropping NetExtender connections from my SonicWALL SRA as being spoofs.
Why?
Answer: If the NetExtender addresses are on a different subnet than the X0 interface, a
rule needs to be created for the firewall to know that these addresses are coming from the
SRA appliance.
Is the SRA appliance a true reverse proxy?

browser is the client. VNC, RDP - ActiveX, RDP - Java, SSHv1 and Telnet use browser-

client.
