Hi guys,
We have 1 SDWAN system as below diagram:
LAN1---Core 1 -------- cEdge1 ----transport sdwan----cEdge2-----Core2---LAN2
With:
- Cedge 1 have ipsec tunnel to cEdge2 by default of sdwan.
- Core 1 have gre tunnel with Core 2.
Actually, we tested: Gre tunnel of Core1-Core2 is up and we can ping between LAN1 and LAN2. But LAN1 can't access service of LAN2.
I checked in cEdge1 and cEdge2 with ipsec tunnel mtu 1441 and tcp-mss 1361 (automaticlly setup by sdwan system).
Any suggestions for this case?
Thanks all guys!

Yesterday, I changed mtu and tcp mss in gre tunnel as below:
Interface tunnel (GRE)
ip mtu 1400
ip tcp adjust-mss 1360
And the service is ok now.
