You can also allow access to the dedicated nic on the backend by
setting up routing to it via the backend box. That would allow access
to the hdhomerun from anywhere on your network. That would require
that the backend box and its hdhomerun network use static IP addresses
or manual DHCP addresses, but you are probably doing that already. The
backend box would need its firewall to allow access, if it has one.
Then you can just run a routing daemon on both the backend and
frontend boxes - I use quagga. You would set up quagga's OSPF
protocols (ospfd for IPv4 and ospf6d for IPv6). You could also use
the older RIPv2 and RIPng protocols, but OSPF works better. If you
want Windows boxes or other devices to see the dedicated nic, then you
would need to set up your router to do RIP or OSPF (if it has that
ability) and those devices would have to send their traffic to the
dedicated nic via the router.

It is also possible to just manually set up routing rules, rather than
using routing protocols to set up the rules.

Good thought, I have ipv4 routing setup and can on Linux access it
through a browser. For some weird reason not on Windows, neither on a
browser nor with the hdhomerun native windows tools. The latter looks
logical as I can not give an ip address there, so it either only
checks the subnet or uses some other discovery method that does not go
beyond the physical subnet.

I'll have to check and compile the latest linux tools as they are old
and also only present on the backend. However checking it, it looks
like I there can supply an ip address.

I'm gonna try things.

I previously never really looked at the hdhomerun_config tool. It says
it wants an <id> and that didn't work in my network configuration,
except on the backend. However <id> means either the id or the ip
address! So I now can in my scripts substitute the old ivtv and v4l2
tools. Will take some time to figure it all out as those script are
old.

Thanks Stephen for kicking my thinking on the right track!

I found the following script (I guess I at some time got it from
silicon dust) and it works perfect!
I put the ip address in hard and the tuning parameters you can get
through:

hdhomerun_config <ip-address> scan <tuner>

I have been looking at it on and of for years, but never really
serious. There was no urgency. I never thought it would be so simple.
Just substituting id with ip! :-)

hdhr4.sh
#!/bin/bash

id=${id:-"192.168.223.20"}
tuner=${tuner:-3}
channel=$1
program=$2
output=${3:-"-"}

usage () {
echo "$0 <channel> <program> [output]"
echo "ENV variables: id, tuner"
exit 1
}


if test -z "$channel"; then usage; fi
if test -z "$program"; then usage; fi


echo command: $0 $*

hdhomerun_config $id set /tuner${tuner}/channel $channel
hdhomerun_config $id set /tuner${tuner}/program $program

if test "$output" = "-"; then
hdhomerun_config $id save /tuner${tuner} - | mplayer -fs -
else
echo Saving $channel-$program to $output
hdhomerun_config $id save /tuner${tuner} ${output}
fi

exit 0
