Hello world<br><br>I have a tough question here, I'm searching from any valuable information on this...<br><br>1/ A host has already IP conection (IP address IP1)<br><br>2/ The host establish a IPSec connection to a SeGW/VPN. As part of the tunnel establishment it gets a new IP address IP2 (tunnel inner address) in the IKE exchange (fields internal_ipv4_address)<br>
<br>3/ Now the host wants to discover the SIP servers (P-CSCF in 3GPP IMS). The clever guys in 3GPP said that it can do it by using DHCP with option 120.<br><br><br>Question : Can the host DHCP just for the purpose of getting the SIP Server address (with option 120) but don't interfere with its already allocated IP address by another entity & method ?<br>
<br>Thanks,<br><br><br clear="all">Sorin<br>
