I suppose so. After returning back to the 'pure' JNOS without BPQ (but 
using AXIP link in JNOS instead), I have forwarding in operation again.

Keep trying that. Btw, is there a precise and detailed explanation of 
all details and lines within config.h because I am not sure what I could 
decide to #undef and/or #define?

I have HIMEM.SYS here. Is it more suitable? The idea was to put BPQ in 
XMS ('lh bpqcode' or like) as well as network card drivers and, if 
needed, make XMS undefined in JNOS (if it may help).

My CONFIG.SYS looks like that:

shell=c:\dos\command.com c:\dos\ /p
rem device=c:\net\ifshlp.sys
rem device=c:\dos\ansi.sys
rem shell=c:\dos\command.com /p /e:1024
rem lastdrive=z

Are the values for files and buffers ok? What about two 'shell' options? 
Which one looks better? (I forgot which software added each of them, so 
I am not sure about proper using either).

Btw, the 'mem' command returns:

626976 largest executable program size
327680 bytes available XMS memory
MS-DOS resident in High Memory area

Any improvement somebody could suggest here .. ?

I do not have EMS at all. Only XMS.

1MByte (1024 k) RAM only ...

Yep, I also have cca 120KB now after booting JNOS without BPQ.

I am not sure about that part. Which netrom table?
