multiple isp and any connect

ISR C1111  with build in LTE modem and any connect

an external LTE modem either in passthrough mode or as a router 

i am unable to get it to work so that i can connect through anyconnect to the C1111

the annyconnect is trying to use the wrong connection as back channel and the ike negotiation 

times out after a bunch of "Packet is a retransmission"

remember when I mention in my previous comment for your previous post, that you may face asymmetric traffic.
so 
we need to match the NAT with route to use both same interface otherwise you always face asymmetric issue. 
so instead of default route use PBR 
this is the traffic pass through Interafce-1 we will use NAT overload Interface-1
that simply the solution for your issue.

Post the configuration, if you turn off other connection and use only required ISP, is that works ?

any connect works as long i have just ONE default gateway removing the one from the external lte and i can connect to the internal and vice versa

post the config also we need to see how your routing configured.

if you have loadshare between ISP, that may have casused the issue here.

 

until we see the config, i do not like to comment any furtehr or advise here.

my current main concern is solved (using 2 isp at the same time for internet connection) by using pbr

but is still wouldnt now how i could pbr any connect 

where would i put the policy?

interface Virtual-Template1 type tunnel
description Cisco AnyConnect IKEv2
ip unnumbered Loopback1

on the virual-templat on the loopback on the lte interface

no real concern any longer but still
