I can only browse google.

Hello my friends i have a problem, i big problem in fact, i can only browse google, when i type words in the addred bar google instant comes up and autocomplete, but when i click on some link it tries to load but it fails, this is in every web browser, i have 2 dsl modems in bridge mode and 2 pppoe clients in each interface. my configuration:

ip address print
Flags: X - disabled, I - invalid, D - dynamic

ADDRESS NETWORK INTERFACE

0 192.168.254.1/24 192.168.254.0 br_LAN
1 D xxx.xxx.xxx.xxx/32 xxx.xxx.xxx pppoe-out1
2 D xxx.xxx.xxx.xxx/32 xxx.xxx.xxx pppoe-out 2


/ip firewall nat
add action=masquerade chain=srcnat comment="Masquereade General"


I would apreciate any hel on this issue, its driving mi nuts. Thanx

Update:

I revert to its original state my isp modem/router (telmex mexico) so he do the dialing and in my mikrotik change my wans from ppoe to static private ip from my isp modem router, now all its working fine, to bad that i can have my public dinamic ip on my mikrotik, i think it has to do with all my pppoe having the same gateway, anyway if somebody got the solution to this problem i would greatly apreciated, greeting from mexico!!
