routed RIS server

[Guest]

Hello all,

A customer asked me to figure out why ris isn’t working and the problem is
called routed network. My question to the real guru’s is the following:

There is a network with multiple vlan’s those vlans are securely connected
via an firewall. On those firewall the following ports are open:
BINL 4011 UDP
TFTP 69 UDP
Netbios 139 TCP
SMB 445 TCP
LDAP 389 TCP
When we start a RIS session it starts and after that it will try to start a
connection on High ports, those ports are random. We don’t want to open all
high ports is there a sweet solution for this problem? We are talking about
10 VLAN’s so it is not preferable to have a ris server on each VLAN.
The firewall is not a PIX firewall

Please help me out here.

Thanks

Eric

I use a linux based server for RIS and I can tell you that this solution
works without high ports (except for BINL which uses a fixed high port).

Maybe a free Linux server is an option for just that purpose?

this is for now not an option, it will be later in a year maybe but not for
now, is there a way to manipulate the tftp deamon?

thanks
