pptp connection as default route (gateway)

Hello,

It has been a long time since I have been strugling with this issue…

I would like to route all the traffic on my router through a pptp connection. I have sucessfully done it in the past on RouterOS 3.12 x86; however, the same configuration over V4.12 is not working.

Right now I am working on a routerboard 493G and I have successfully created most of the setup. A main interface (bridge) which puts together an internal AP card and eight ports as a switch, I reserved the las port for the Wan interface.

I successfully assigned an static ip to the bridge (192.168.50.1) and added a client DHCP on the Wan port for obtaining a public address from my ISP. (add default route - yes)

Then I set up the pptp connection (add default route - no) I manually added a default route by using the pptp servers ip as gateway and attached it to a new routing table named lan_traffic. After that, I marked the connection on the bridge interface as a first mangle rule followed by a second rule, a routing mark to send the marked connection to the routing table lan_traffic.

Finally I Natted the pptp interface (out connection) with masquerade so it could be shared among my local clients.

At the end of the day all my clients are not able to browse the web…

Pptp link is successfully established, I can ping external ips and resolve hosts…when I open a web page I takes a long time to load and most of the time it just does not load at all

What catches my attention is that the same configuration works flawlessly on a virtual machine with routeros 3.12 x86…

I have read all the forum looking for an answer or an alternate solution that could help me but nothing has worked…

Any ideas on how to make this set up to work would be appreciated.

Maybe you facing up with MTU problem. try to lower TCP MSS througth firewall mangle.

Hello,
Do you found a solution for this problem i have the same as you i wish you could help me now??

Whaaaao I cant beleive I spent months without being able to solve my problem and lowering mms through mangle did the trick!

Here is an example on how setting up the rule:
http://wiki.mikrotik.com/wiki/Manual:IP/Firewall/Mangle#Change_MSS

Go to the link and follow the instructions…just change the pppoe interface for your pptp connection. I used 1300 for the new mms value as in the example and worked!!!

/ip firewall mangle
add out-interface=pptpinterface protocol=tcp tcp-flags=syn action=change-mss new-mss=1300 chain=forward

Thanks for the tip enk! I do appreciate it!

Cheers!!

what if i created it and it does not count at all, what i miss?
