Hi All,
Just to Update,
Reload the router and SSL VPN worked correctly.
May be was some issue with MTU like TheEther say...
Will continues to monitor if it will happen again will update.
Thanks for you all for trying to help.

Well, the same thing is happening on the LAN side. The remote peer is not responding correctly to the TCP 3 way handshake. This seems to rule out the router. Perhaps you can capture the packet exchange without the router, since you claim things work.

The latest capture looks like a healthy connection establishment. There is one odd thing. The source address is 192.168.43.168. With the router removed, I would have expected the source address to be 31.x.x.x, as before. Where is this private address coming from?

Hi TheEther,
i was using 4G connection from phone,
That why was address 192.168.43.168
if need i can do PPPoE directly and show you the results.

Feel free to run it. If it looks the same as the last one, there's no need to post it. Do you have another router that you could test?
If you want to put the pcap files some place that I can access, I can take a look.

Hi TheEther,
yes it's look like the same one.
Yes i have the old Cisco 861W and i check with it and SSL VPN worked correctly.
when you will have time look at files and update me if you find something if not i will reboot the router probably all will work.the link to dropox i send you privately.
Thanks,
