[Modbusfw-talk] Re: unresolved symbol

[Venkat <vpo...@ci...>]

Hello Alex,

The modbus module is dependent on the underlying iptables modules, so 
you need to insmod the core iptables modules before loading the modbus 
module.  I dont remember the exact sequence and which module has the 
register and un_register functions, but in any case, I think you need to 
load  ip_tables.o, ip_conntrack.o, iptable_filter.o and ip_nat_core.o 
before loading ipt_modbus.o.

Thanks, -Venkat.
