Guest network and mobile access on same public IP

Hello,

This configuration is set on R80.10 version. 

I have a guest access with NAT IP public, this access is for web access with some limitations.

But somes times, internal users as don't have access to internal network , use this guest access to connect to VPN ( this VPN is a mobile access and configured with the same public IP of guest access ), but not works. 

Checking logs I see that all traffiic is drop because anti-spoofing protection. 

Do you know it's possible to make this configuration without disable anti-spoofing protection  ? 

Thanks in advance, 

Marco

Re: Guest network and mobile access on same public IP

A few more details are needed here.

  • Is your guest network included as part of the Encryption Domain (Gateway object > Network Management > VPN Domain)
    • If you're using All IPs Behind Gateway, then it is and you should use an explicit domain definite that excludes this network.
  • A screenshot of the anti-spoofing message would be exceptionally helpful along with related topology information

Re: Guest network and mobile access on same public IP

Hi, 

Network guest is not part of encryption domain and for mobile access I using a specific domain and not include the guest network.

This is the message with drop packets. 

Thanks,

Re: Guest network and mobile access on same public IP

Need to see the entire log card, not just the message.

Also need to understand the topology.

Hi,

Thanks for your help. 

I solved my issue with sk44075. Apply solution for Cause 2: Office Mode IP Pool is part of the VPN Encryption Domain

Thanks,
