Packet forwarding between two ethernet ports

[Jeremy Begg]

Hi,

Process Software MultiNet V5.1 Rev A-X, COMPAQ AlphaServer DS20E 666 MHz,
OpenVMS AXP V8.2

This system has two 100Mbit ethernet ports, one on 192.168.1.0/24 and one on
192.168.2.0/24. Currently MultiNet is configured so that they are isolated
from each other, i.e.

$ mu set/kernel IPFORWARDING 0

is done in MULTINET:LOCAL_ROUTES.COM.

The site operates a VoIP network which is contactable via the 192.168.1.0
network. They now want to add some more VoIP phones which for various
reasons *must* be on the 192.168.2.0 network.

So the first thing we'll need to do is re-enable the IPFORWARDING, I assume.
I'll also add some packet filters to limit the forwarded traffic to the VoIP
stuff.

My question is, will MultiNet forward UDP packets from one network to the
other? (I don't know if UDP is a requirement, I just thought I'd ask!)

Thanks,

Jeremy Begg

Yes, it will forward UDP and all other IP protocols.
