Hi there, I'm having a really strange problem with otrs. I'll try and describe the simptoms: Otrs is installed on http://192.168.1.73/otrs/index.pl There is a port forward on our router to access it externally through http://external_ip/otrs/index.pl On some workstations I can access the whole system just fine. On some other workstations I can access the system, login, view tickets etc... But I just can't submit any forms. For example, if I try to set a note on a ticket, or reply to a ticket or forward a ticket, etc when i clock the submit button the system just timeouts after a while. If I watch the apache log as I'm clicking the submit or Send mail button I get no log activity. Stranger thing is: on these computers that have this problem, if I access it through the external ip, everything works fine. Unfortunately we won't be keeping the external access and all i wanted was really to access it through the internal ip without these weird issues. Any ideas? I think I've tried just about anything. There was this post a few years ago on this mailing list with a similar problem: http://lists.otrs.org/pipermail/otrs/2008-June/023664.html Unfortunately there is no resolution or hints on what can be wrong on that thread. Thanks Luís Gomes
