please bear with me...i am a newbee when it comes to netscreen.

i switched out my SMC Barricade for a NS 5XP on my home network. since doing this, i have not been able to create remote desktop connections back to our corporate office.

the way we usually connect to the corp office is to establish a checkpoint secure remote VPN. this is invoked by launching the RD session at a private IP back to our office. after establishing the VPN, i am able to telnet to these corportate hosts private IPs over port 3389, this tells me i can get there (after all was able to using my old SMC gateway). i believe the NS 5XP is blocking the traffic coming back.

on my NS5XP i created a new RD service with src ports to be 1024 thru 65535 and dest port to be 3389. created a rule for trust TO untrust and untrust TO trust. tried specifying both ANY service and the RD services i created. i dont see any trafic using these rules when viewing the NS policy reports and traffic is being stopped somewhere.

we also use Citrix ICA published apps and i have no problems even though ICA RDP and UDP services are not defined on my NS.

i am new to NS and think i have not set something up properly. i am not trying to create a NS to Checkpoint vpn. just trying to use my little VPN client/Remote Desktop thru the NS.

i tried looking through netscreen (Juniper's) web site but couldnt find anything there i havent already tried.

if there are any NS savy folks out there who could help, i would really appreciative it. i can send you my NS 5XP config and tech-support config files along for further examination.

thanks in advance!
 
thanks to Packet7 who pointed me in the direction of netscreenforums.com. my issue turned out to be an MTU setting in my Checkpoint SecuRemote client. i changed it to 1300, which matched my NS 5XP and now my remote desktop sessions open!!!

thanks P7. you get credit for this one!
