- It should not be a problem if the net is transparent (i.e., if the 'gateways'
- you are talking about are repeaters or bridges). If you have routers
- in between which block udp and other services, you will need to open
- them up individually if possible. If you have REAL gateways (i.e.,
- protocol translators) you must be damned lucky to get it going.
-
- In my network we had a probmen with UDP and broadcasting across a cisco box.
- I made it work accross the boxes by announcing the load host via
- a helper address, in the config this reads as
-
- (on the interface towards subnet 1)
-
- ip address 131.152.1.249 255.255.255.0
- ip broadcast-address 131.152.1.255
- ip helper-address 131.152.8.1
-
- if the load host is 131.152.8.1 and the machine I want to load is in the
- 131.152.1 subnet.
-
- Maybe this helps, forgive me if I'm wrong, but it worked for me.
