  • Alcatel STP and NAT

    Hi everybody, I have a problem and I hope someone can help.
    I have an Alcatel SpeedTouch Home modified to Pro between LAN and ADSL; the connection is on the ATM provider's network running in CIP mode. I have an 8-address public IP class too (217.114.235.88/29).

    This is the router's configuration:
    10.0.0.138/8 default administration IP
    217.59.218.154/30 external IP connected to provider's router (217.59.218.152)
    217.114.135.89/29 internal gateway IP

    This is the routing table:
    Destination Source Gateway Intf
    217.114.135.88/29 217.114.135.88/29 217.114.135.89 eth0
    10.0.0.0/8 10.0.0.0/8 10.0.0.138 eth0
    255.255.255.255/32 any 10.0.0.138 eth0
    217.114.135.89/32 any 217.114.135.89 eth0
    10.0.0.138/32 any 10.0.0.138 eth0
    217.59.218.154/32 any 217.59.218.154 cip0
    127.0.0.1/32 any 127.0.0.1 loop
    217.59.218.152/30 any 217.59.218.154 cip0
    217.114.135.88/29 any 217.114.135.89 eth0
    10.0.0.0/8 any 10.0.0.138 eth0
    default any 217.59.218.152 cip0

    Dial-in, PPP, PPTP and Bridge are not defined.
    All runs well while I use my public IP address for the LAN's PC; however there is a lot of security problem.
    To use private IPs in the LAN, I think I need enable NAT, though I have no server to show in the Internet. The CLI manual shows whole command syntax but examples are not very useful.
    Common suggests say to use "nat enable addr=217.59.218.154 type=pat", but all I've done gives no results.
    What can I do?

    Thanks
Working...
