SSL problem with EOIP over L2TP VPN

Tue Mar 28, 2023 3:43 pm

I am having issue opening some ssl sites like mail.yahoo.com, gmail.com and others (but not all ssl sites) from clients which connects on EOIP over L2TP vpn connection from TP Link LTE router. My L2TP MTU is 1450 and EOIP is not set and takes default value of 1408. Ping and other non ssl sites work fines but as I mentioned earlier some ssl sites are not opening but i can open google.com.
What is the problem here and what is the solutions. I am using router os 6.48.6 long term. My clients router is RB750GR3 (3 clients) and Central Router is CCR 1036-8G-2S+

I tried that also but issue remain same. What is very strange is that i have 3 remote sites where one is working perfectly without issue with the same configuration.

Problem has been resolved by changing different LTE router.
