any suggestions on this appreciated....

[Seabatt]

set this up on single system worked fine,
attemping to set up private server on other system..through lan connection, 5 port hub..
have read just about every post on the boards..tried everything
here is the problem
I can connect to the private server..usually says its locked, but still can get to character creation screen..all that works fine..
but as soon as trying to enter the world..it kicks me right back to
the server selection screen.
So ive tried every combination I can think..of. with ip's, the 127.0.01, localhost..etc....
yes , all of them..
any new ideas would be helpful.
would also like to know what this Unknown opcode a lot of peeps seem to be getting..
seems they are always Ox35121,3921, size 2056 etc.
maybe i could be more detailed but ive been working on this for 8 hours straight and need to go get some sleep.
:o
thanks all for any assistance
