Do you use an Apache server and have access to your htaccess file in your root directory of your server?

If so, you can map your old address to the new one this way (assuming I got your links right):

Redirect permanent /Foro-de-viajes http://www.viajeria.com/foro

or generically:

Redirect permanent /old_directory http://www.xyz.com

See here for other examples on how to do:

Yes, if you are getting that logout issue it is most likely that you are not using the correct bridge version.  You have to have JSMF 2.0.2.1 for Joomla 1.0.13.  Joomla! changed their password hashing which required a hack to make the bridge work again.

Should be using version 2.0.2.1 if you are using Joomla! 1.0.13.  Try that (see link below) and  see if that fixes the issue.

As for the prefix for the database, my SMF/Joomla combo works fine with just "SMF_####"  e.g., SMF_members (etc..etc.) for the SMF entries (SMF and Joomla entries must be in same database). 

Working well with my install with no errors. 

Thanks for the work on the patch! 

Joomla:  1.0.13
SMF:  1.1.3
Gallery 2:  2.2.2 (also embedded into SMF for linking photos)

Well, there is nothing really to convert, per se.  I have used both bridges at one point or the other.  Just need to make sure you go back to the JSMF component in Joomla backend admin and select the "Install" menu.  Then look at each of the options on that screen and make sure to "unpatch" each selection in the install screen.  Then things should be as they were prior to the bridge/patch.  You can then use the official bridge instructions at the SMF website to install from that point forward.  I would uninstall the JSMF component once you got things working the way you want. 

I will say that I had a heck of time with the Orstio bridge (earlier versions) and it whacked out my SMF forum inside the Joomla template.  So make sure you have backed up your SMF and Joomla folders on your website before you start messing around with their bridge. 

Of course, with the politics of Joomla/SMF at the moment, you will get no Orstio support since they are fighting over license  issues and the bridge has been taken down (hopefully only temporarily).
