Hello,
We have an issue on DMVPN setup on which all traffic is working normally between Hub and spokes except for some specific web application, the login to application page is working also fine and page is accessible but when trying to download some PDF file , it starts download first couple of KB's then it stucks.
DMVPN configuration is based on best practices by Cisco.
For troubleshooting purposes two tests were done :
1. First Test : we tested the same exact configuration on different provider link (let's call it provider B) between a one spoke (this same spoke was having the problem with the other provider let's call it A) and the same hub, and this application was working just fine.
2. Second Test : we disabled DMVPN cofniguration between HUB and spoke and simply built Static IPSec VTI tunnel between the same pair of devices and using provider A link ; it was working fine this time although it was not working when using DMVPN on same provider A.
Appreciate to share your knowledge and thoughts on this ; what is the difference between Static IPSec VTI and DMVPN that may cause this kind of applications not to work properly.
Best Regards,
Muayad Jallad,
