Ethernet Shield socket ENC28J60

Hi is it not possble to use port 81 on my arduino Ethernet Shield socket ENC28J60 webserver? I tried the port 80 then it works, but im using another server on that port.

static uint8_t mymac[6] = {0x54,0x55,0x58,0x10,0x00,0x24}; static uint8_t myip[4] = {192,168,1,41}; static char baseurl[]="http://192.168.1.41/"; static uint16_t mywwwport =81; // listen port for tcp/www (max range 1-254)

ohhh i found out why...

don’t leave us hanging!
