have you tried only bfgminer (2nd gen), one guy in my pool is using 1 PC for 1 blade (for CPU to catch up) and he uses bfgminer with
"--http-port 1234" option and on blade config simpy points his blade to PC IP address and same port (1234).
he is one of top miners if I'm not mistaken.
EDIT: so in your case it is:
bfgminer --http-port 1234 -i ibipot.com:3333 -u user -p password
and on blade:
IP 192.168.1.108:1234
user and password also on blade setup to match the pool worker and pass
It does work ,but only get 2-3G hastrate with which supposed be 8G
I tried another way(Mcproxy3+mining_proxy+BFG1), I can get full speed ,and HW is low ,but accept is too low , the hastrate shows on the pool also very low
wondering which version of mcproxy are combined with BFG2?
hope DEV can improve the BFG2 performance later
what CPU you have? I will ask config from that guy, how many PC's he has and what cpu and etc.
