Need help on Firewall 1/VPN 1 NGX

[rrudrapathi]

Hi,

I am really new to this area. Don't scold me if anything is wrong. Guide me please...

I have configured VPN1 (NGX) server(Dual card) and tried to authenticate a protected resource from the client. Am getting Gateway not responding... if I enable Antispoofing for internal network. If I disable Antispooling then authentication is going fine. Please help..

VPN server Configuration:
====================
Internal IP: 192.168.10.20
External IP: 172.16.146.20
Default Gateway: 172.16.146.1


VPN Client:
=========
Client IP: 172.16.146.17
Gateway for Client: 172.16.146.1

Thanks,
Raja.

What setting do you have for the antispoofing on the external interface?

SecureClient cannot be on the same subnet as the gateway's external interface. I don't know if using 255.255.255.255 for SecureClient and the gateway will work, though.
