  • 1.  GRE tunnel between Aruba and PaloAlto firewall - no encaps

    Posted Jan 18, 2021 11:31 AM
    Hi community 

    We try to establish backup link between office and DC on LTE using GRE Over Ipsec and then running OSPF. 
    We have in-line also Ipsec established but not on Aruba controller but Fortigate LTE extender module working as router with NAT.

    We configured GRE tunnel between PalAlto firewall and aruba controller. 

    it shows that tunnel is up also we can see traffic from Palo to aruba on datapath session table but when we see interface stats I see generaly only Decaps, no Encaps on tunnel interface. It seems like controller doesn't want encapsulate traffic from some reason.

    Does anybody know what can be the reason of such a controller behavoiur ?

    Regards

    Karol
