>Many confused configurations.
>
>1. If the ISP assigns 192.168.0.11 to WAN, the LAN IP should use different IP range.
>2. Make sure just one DHCP for LAN.
>3. DDNS space should hostname.dyndns.org.

>  Question 1:
>  Is it possible to create a VPN Connection from the outside using diaup to a
>  network using a WRV54G Linksys VPN Router with a DHCP Connection (non-static
>  IP) and DDNS (dyndns.org)?
>
>  Our goal is to give both (and only the two) VPN users access to the complete
>  network via an internet connection.
>
>  When we added the VPN Users in the router all of our internal Network IP's
>  changed from 192.168.1.xxx to 10.56.182.xxx. Subnet Mask stayed the same at:
>  255.255.255.0.
>
>  The DHCP connection is provided by Hughesnet Sattelite Service and gives the
>  IP as 192.168.0.11 on the router's WAN IP Address.
>  DW7000 Info:
>  LAN1 IP Address: 192.168.0.1
>  LAN1 Subnet Mask: 255.255.255.0
>  NAT IP Address: 67.46.190.117 (the sattelite modem)
>  NAT Subnet Mask: 255.255.255.255
>  Router Address: 67.142.137.152 (the router itself)
>
>  When addressed directly in the browser:
>  67.46.190.117 brings me to the Sattelite Status page, the same as 192.168.0.1.
>
>  67.142.137.152 bring up "Failure To Connect To Web Server"
>
>  We have signed up with dyndns.org and subsequentially we given the xxx.
>  dnsalias.com, and have activated this in the router's Setup\DDNS page. The
>  results are:
>  DDNS Service:   DynDNS.org
>  User:   setup at dyndns
>  Pass:   setup at dyndns
>  Host Name: xxx.dnsalias.com
>  Internet IP Address:   192.168.0.11
>  Status:   DDNS is enabled.
>
>  We have gone into the applications and gaming page of the router and
>  forwarded port 1723 TCP to the internal network address of 10.56.182.0. I
>  'dunno if this is correct, but I saw this in many posting on this and other
>  sites.
>
>  We have also Set IPSec, PPTP, L2TP to enabled in the router. Although, all we
>  really want/need is the IPSec availability.

>  Question 2:
>  Do we need to place xxx.dnsalias.com in the router's setup page Domain Name
>  space as well?
