ISAKMP drop by ISP

Post by masoud » Fri Oct 07, 2022 8:05 pm

Hi there

I have configured softether on ubuntu, and I can connect via its client program without any problem on my desktop.
But when I want to use l2tp over iPhone it doesn't work!
I used Wireshark and I realized ISAKMP never reached the server and it's blocked by ISP due to filtering.
Is there a way so can use other authentication protocols besides ISAKMP?

Thanks for your valuable time.
