Please help - new router now can't access

My employer (hospital) uses Lawson SSL VPN.   I had no trouble connecting at home from my old Windows 7 laptop and my new Windows 8.1 desktop with my old Linksys WRT-120N router. 
I just bought a new router Linksys E2500 and now I can't connect to Lawson anymore.
I put the old router back on and it works. 
Any suggestions how to get connected with the new router ? 
It has a section for VPN passtroughts.  They are All enabled.  I tried disabling the IPv4 and IPv6 firewalls.
I enabled PPNT on the port forwarding page.  I've tried everything every setting .
Please help.
Thank you very much for any advice.  I get to the Lawson sign in page, but then a blank screen pops up, with script error.  I've allowed pop ups, and scripting in the internet options settings but as I mentioned i get connected with the same computers when i change back to the old router (which by the way has no options for passthroough  ).
This is the version of Lawson i think  ...
