[AusNOG] IPsec issues over Telstra

We've done it a bit (and are currently running some) on Telstra.internet (if I recall correctly) using DMVPN with Cisco gear to do it, so its not an exact match to your situation.

Never noticed any specific IKEv2 issues though.

I can do it (IKEv1 though) with the embedded LTE modem in a FGT
30E-3G4G-GBL, but if I use a Netgear LB2120 connected to the FGT, the VPN
doesn't come up (I haven't investigated further yet due to lack of time).
