i am running win xp behind a broadband->modem->router.

i setup up my IIS port TCP port to 1515.

my computer name is yccheok

when i type, "http://localhost:1515" in my web broswer, fine, it works!

when i type, "http://yccheok:1515" in my web broswer, fine, it works!

however, when i type, "http://10.0.0.9:1515" in my web broswer, OPPs, it does not works!

it will prompt out a dialog box requires me to enter username (with 10.0.0.9\admin as default) and password.

strange. it look like my broswer is dialing to the router. however, 10.0.0.9 is not my router address. (my router address is 10.0.0.2)

i run ipconfig and ping yccheok, they give me the result of following:

Windows IP Configuration


Ethernet adapter Local Area Connection:

        Connection-specific DNS Suffix  . :
        IP Address. . . . . . . . . . . . : 10.0.0.9
        Subnet Mask . . . . . . . . . . . : 255.255.255.0
        Default Gateway . . . . . . . . . : 10.0.0.2


Pinging yccheok [10.0.0.9] with 32 bytes of data:

Reply from 10.0.0.9: bytes=32 time<1ms TTL=128
Reply from 10.0.0.9: bytes=32 time<1ms TTL=128
Reply from 10.0.0.9: bytes=32 time<1ms TTL=128
Reply from 10.0.0.9: bytes=32 time<1ms TTL=128

Ping statistics for 10.0.0.9:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 0ms, Average = 0ms

it seems that 10.0.0.9 is my private address. 10.0.0.2 is my router address.

please note that i didnt use any port forwarding in my router. ya, i do use NAT in my router.

may i know how can i solve this problem by enable me to take 10.0.0.9:1515 to refer to the IIS server. not router.

thank you.

Try ipconfig /all
it may give you a clue.

also, try  tracert 10.0.0.9

Right, it seems that XP is trying to do an IP to name resolution, but as the Router is a caching only DNS system, that will not work.
The only way around this is to have a local DNS server, or to insert an entry in the arp cache.

arp -s <macaddress> <ipaddress> may work.
