Hi, I have a problem with IPSEC VPN:
I can not access the local web site through VPN from two of branches and see " web site cannot be reached ".
I found out the acceptable MTU size on these branches is less than 1500 ( around 1300) so:
I changed the MTU size on the Cisco Router (small business ADSL) to manual 1300
and changed the computer MTU to 1300
also on sophos UTM9 selected "Support path MTU discovery" and also tried without that ...
but the problem not solved yet. I feel really frustrated :( :(
Can you please help me?
