I have a computer with 2 IP-Addresses (and one LAN adapter). The client sometimes has to use the first IP address and sometimes the second IP address. How is it possible to implement that, since the client binds automatically to the primary IP address of LAN adapter (IP stack). Thanks, Uli Back to top Remy Lebeau (TeamB) Guest Posted: Mon Apr 05, 2004 7:28 pm    Post subject: Re: Specifying Client IP Address with Indy "ug" <ugarbe (AT) vt4 (DOT) net> wrote Quote: Is it possible to specify the IP address a client (TIdUDPClient, TIdTCPClient) uses when sending/receiving data?

Only when you don't specify your own binding info prior to opening the connection.

It will give you the host name of the server. You are thinking of the PeerIP property instead: AThread.Connection.Socket.Binding.PeerIP However, either way this does not address the actual issue that ug is asking about.

For IdTCPClient the solution works. For IdUDPClient I'll test it this week.

I assigned the 'second' IP address of the computer to SNMPClient.Binding.IP but the request is sent out with the 'primary' address. Is there s.th. I'm missing? The second IP address is assigned to the interface, and works well with TCP clients. This is the code: SNMPClient.Host := ServerIP; SNMPClient.Port := ServerPort; SNMPClient.Binding.IP := ClientIP; SNMPClient.ReceiveTimeout := timeout; SNMPClient.QuickSend(MIB_String, Community_String, ServerIP, Receive_String); Uli "Remy Lebeau (TeamB)" <gambit47.no.spam (AT) no (DOT) spam.yahoo.com> schrieb im Newsbeitrag news:4071b35c$1 (AT) newsgroups (DOT) borland.com...
