This is exactly what I'd expect -- these two OIDs do not resolve to
integers, but to an OID and a string.  You need to use different OIDs; also,
be mindful of if oyu need to use option 'gauge' in MRTG (if your target OID
is not a counter)

These two say that MRTG is unable to identify the interface number for an
interface with the name 'X1'.

>iso.3.6.1.2.1.2.2.1.2.2 = STRING: "LOOPBACK"
>iso.3.6.1.2.1.2.2.1.2.4 = STRING: "X1 (WAN)"

>iso.3.6.1.2.1.2.2.1.2.10 = STRING: "U0 (Unassigned)"

This is your ifDescr tree, and it shows that the interface name is actually
"X1 (WAN)" (and ifno=4).  Have you change your interface descriptions since
you generated the MRTG cfg file?

Here's your current Target definition:

Target[192.168.30.1_X1]: #X1:xxxxxxxx at 192.168.30.1:::::2

Try to modify it like this to use the full interface name (you need to
escape the spaces of course)

Target[192.168.30.1_X1]: #X1\ (WAN):angrybird at 192.168.30.1:::::2

If this doesn't work, then try this version, which forces use of the
interface number (be careful as this may change if you modify the hardware)

Target[192.168.30.1_X1]: 4:xxxxxxxxxx at 192.168.30.1:::::2
