I have EMM 1.1.0 installed on server with internal IP 10.100.0.1:9443. Port forwarded by router to external IP 90.90.0.1:23333
Im able to log in locally to https://localhost:9443/emm without a problem.
Cases:
1) After modifying all localhosts in sso-idp-config.xml to internal 10.100.0.1:9443
From internal LAN to //10.100.0.1:9443/emm - able to log in
From external to //90.90.0.1:23333/emm redirected to //10.100.0.1:9443/samlsso - failed
2) After modifying all localhosts in sso-idp-config.xml to external 90.90.0.1:23333
From internal LAN to //10.100.0.1:9443/emm after log in redirected to //90.90.0.1:23333/emm/acs - failed
From external to //90.90.0.1:23333/emm login?null redirected to //10.100.0.1:9443/samlsso - failed
What is strange is that iam able to reach //90.90.0.1:23333/carbon from external side in both cases.
