Site-To-Site connectivity and application access

[BSBhatia]

Hi

After migration to checkpoint firewall 5900 (R80.10) at two geographically separated sites, network access from one site to another does not work, when the tunnel terminating on the edge routers of the two sites is in place. But as soon as the tunnel is removed between the two edge routers network access is enabled and applications across the sites become accessible.

Kindly help to fix the issue.

Thanks
