NAT masquerade.

Hi;

is there any wiki example page ?

slightly different, but explains the nat setup.

Can anybody help me?

I tried NAT but I couldn’t reach internet by router.

thanks.

sergejs · March 9, 2010, 6:09am

The problem is with route,

[admin@RB411U] > ip route print
Flags: X - disabled, A - active, D - dynamic,
C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme,
B - blackhole, U - unreachable, P - prohibit

DST-ADDRESS PREF-SRC GATEWAY DISTANCE

0 DS 0.0.0.0/0 81.6.124.185 1

Default gateway is without 'A' sign (active), so it is not working.
I do not know why A is missing, as in your setup it should be with A. You may try to set add-default-gateway=no and add it manually to check if the internet works.
Let us know about the result.

ta2mzl · March 9, 2010, 10:18am

Sergejs;

Thank you for answer;

I will try your advise and I will be inform you.

I have also similar topic in “RouterOS Community Support [General]”.

and I think problem is below; my gateway and dst Ip is same that is comming from 3G provider.

I can not change this. Because that is 3G provider rule and they are giving same IP as dst IP and Gateway IP.

sergejs · March 9, 2010, 12:53pm

Yes, I see that it is from your provider.

As I told you try with static gateway rule.
Make sure the latest MikroTik RouterOS version is installed on the router.
Contact your provider to clarify, whether they haver proper configuration on PPP server on their side.

ta2mzl · March 9, 2010, 6:18pm

Sergejs hi;

thanks for your advice

Problem solved, I can connect 3G network and I can surf Internet via RB411U+MC8790 combination.

Problem was add-default-route=yes, don’t enable that in UMTS interface and add manualy route with gatewat=ppp interface as UMTS connection.

reecho · March 18, 2010, 6:09am

Can you clarify what you added as a route??

This would help me heaps..

adnan07 · March 18, 2010, 10:23am

hello ta2mzl
can you please explain how did you add the static route…coz i’m facing the same problem since last few days.
thanks

ta2mzl · March 20, 2010, 6:41am

hi adnan ;

where are u from?
