netscreen ns5gt (lan 10.0.0.0) behind thomson (lan 192.168.1.0) - how to setup smb to 192.168.1.80.

HI,

I have a modem (thomson, lan 192.168.1.254) which has e synology connected to it (192.168.1.80) and a paasthru to a connected netscreen ns5gt, for vpn access.

what i want is to gain smb acces to the synology thru a vpn tunnel (all setup and working fine)
i have not done this before, so i was thinking to make a mib on the untrust side 10.0.0.252 / 192.168.1.80. tried it doesn't work or show up at the logs, so thats probably a stupid thought.

thanks

if the vpn is setup and working fine you just need a policy that allows the SMB port incoming on the VPN tunnel

if you post your sanitized netscreen config file, i can tell you what needs to be modified so that this will work for you

Your network is very unconventional. let me see if i understand how this is truly setup

you have the juniper untrust 192.16.1.74/24 conected to a modem
also plugged into this modem is your NAS device 192.168.1.80

on the trust side of the juniper you have the network 10.0.0.254/24 what is this network for?

you also have a MIP thats going from trust 10.0.0.252 to 192.168.1.80 (which is actually backwards)


Please let me know if i am correct in what i described or way off.

In my mind this should be setup as such: Modem ---> juniper ----> lan with NAS and other devices
then users can VPN ---> juniper ----> access to NAS devices with relevant security policy (no MIP required)

true, and you fully understand correct. forget about the mib, doesn't work and is deleted (sorry i have send). your right about the placement of the nas, As is implemented the the hardware i had some trouble forwarding the synology ports, and was out of time, so i connected the nas to the modem, so at least thoose functions work. So unconventional yes.

10.0.0.0 network is the lan with workstations and printers attached.

further  i am not at the location, only access is thru the tunnel to the netscreen. from there i need acces to 192.168.1.254 (for modem access) and i need to access the synology from the tunnel.
If its not possible or almost impossible, just let me know, i will visit the location again.

kind regards,
lucien

ok then its looks like you are missing routes on the juniper. if users on the VPn can ping the lan which is 10.0.0.254/24, can they also ping the wan 192.168.1.74/24?

also if you do a get route command from a console session, please post the routing table for me


thanks

can ping 10,0.0.254 not 192.168.1.74. li can ping both from a computer located there, but not from the tunnel .AT this time the netscreen is down, i ques the cleaner needed power (this a new company, nothing there)

thanks for now will be back tomorrow
cheers
