Hello. Please help me…
I have configured 750GL with NAT, white IP and L2TP Server with thise:http://wiki.mikrotik.com/wiki/MikroTik_RouterOS_and_Windows_XP_IPSec/L2TP
All work fine if i connect from my home computer without NAT (ADSL, DLINK with bridge)
But when i try connet with thise scheme (with NAT in my home router):
home comp(XP)->adsl router(NAT, gray ip)->internet->mikrotik 750 (L2TP Server,nat) I got error: 678 Error. Remote comp does not respond.
I open UDP ports on my ADSL router , and i see log permitted udp xxxxx(1701) → xxxxxxx(1701). There is no DENY log…
but i can not connect to router…
Thank you…
I guess you need to enable NAT traversal function.
/ip ipsec peer set 0 nat-traversal=yes
Thank you.It Enabled, and i got: Error 792 - The L2TP Connection Attempt failed because security negotiation timed out.
I try to edit registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\Parameters
ProhibitIpSec (0,1)
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IPSec]
AssumeUDPEncapsulationContextOnSendRule (1,2)
and ..no result.
Is any idea ?
It looks like issue, when I tried to use SSTP between Microsoft and RouterOS. I do not have any idea. I have not solved my issue.
I upgrade RouterOS from 5.4 to 5.14 , change ip sec Exchange mod to “main l2tp” and everething OK!!!
Thank you for you attention…
