IBM RSA through firewall, blank screen in remote control

IBM RSA through firewall, blank screen in remote control

IBM RSA through firewall, blank screen in remote control

(OP)
I am conntecting to an RSA card via a fire wall. When I select remote control, a get the remote control screen, the headers/footers are all there but the screen is blank where I should be seeing the logon prompt.
If I follow the same process to a server on my side of the fire wall everything works.

Has anyone else had this problem? and what is the solution?

RE: IBM RSA through firewall, blank screen in remote control

I would check that the necessary firewall ports for RSA are enabled.  If I recall port 2000 was required for remote console.  Take a look at this;

Thanks for that. Port 2000 was open but there appears to be a conflict with what CISCO uses port 2000 for and the RSA card. This is the comment from our Fire wall techo's

"If the traffic is not SKINNY traffic and it's destined to port 2000. NAT will treat it as SKINNY data. If it's not then, the traffic should not use port 2000"

"tcp_2000 used as skinny port for cisco .  when tcp_2000 is not used as skinny port the nat translation will fail.
no ip nat service skinny tcp port 2000 <---------------- recommended workaround. "
