Thanks Pete,
now coming closer to the issue...
The three mentioned PC´s are physically connected via a seperate LAN card and therefore have got three local IP addresses (180.180.10.99, 180.180.10.100, 180.180.10.101). This network works as all three PC´s can see eachother and their drives. It´s not working via the internet
Nevertheless I now additionally have a WorkGroup and again all three PC´s see eachother. PC3 now got an immediate WideClient connection to PC1/FSX but PC2 WideClient (connected in the same way) still waits for a connection. What´s wrong here as there seems to be no difference compared to PC3 ??
Log from PC2 now follows:
********* WideClient Log [version 6.94] Class=FS98MAIN *********
