Hello,
We are having a stranger problem when accessing by VPN (IPSEC Site to Site) a web application. The WEB application when accessed by VPN stay loading Loading and freeze. After using Wireshark on this server that hosting the web application I could some retransmission events (image attached)
My troubleshooting steps until now:
- Create a DNAT rule on Head office and try access the same aplication by WAN address from Branch office, and the application it works as expected.
- Accessing this application over the same LAN (from Head Office) it works as expected.
- Disable all IPS rules on Firewall Rules VPN-TO-VPN. Not effect, not working
- Change WEB application port on Hosting web server, not working
- Adding bypass stateful firewall rules on BO device and HO device the access it works as expected. (With This I supposed that there iare something on XG device that can be causing it)
All others access (SSH, CIFS, RDP, form BO to HO over this VPN it works)
Could someone has any tip for this ?
Regards
Carlos
