Unable to Access the SAP Server form the VPN tunnel

[Saranya_0305]

Dear Team,

We have Management Sever running in R82 and Central Firewall in R82 in Bangalore.

And there are other SMB appliance which are in  other locations which are centrally managed which are connected through the Central Firewall to the Management Server.

For SMB Internal to we are trying to Connect to the SAP server which is behind the Central Firewall through the VPN tunnel.

SMB Internal:

Internal IP: 

Host1: 10.21.61.7/24

Host2:10.21.61.21/26

For both hosts 10.21.61.1 and Gateway is 10.80.21.5.

Central Firewall:

SAP: 10.10.4.32.

From the 10.21.61.7 we are able to reach the 10.10.4.32, but form the 10.21.61.21 we are unable to reach the SAP Server even though both follow the same route.

When we check the logs the logs are showing accept logs, but we are unable to reach.

Please suggest me on this.

Regards,

Saranya

To begin can you please clarify if Host1 and Host2 are really on overlapping subnets?

[Saranya_0305]

Yeah as per my understanding They are over laping subnets.

I agree with @Martijn since on the basic principles of routing the traffic can't arrive back to both hosts given the information provided as is.

Is the tunnel showing both phase 1 and 2 as up?

[Martijn]

Do you have a simple network diagram showing is the setup?

It will makes things more visible and clear of what you are trying to accomplish.

Dear Mates, 

Sorry for the delay.

Its looks like some NATing issue. Some how we have resolved the issue.

Thank you for your insights.
