I am having DNS issues with this VPN, the Portal is open, and traffic can flow correctly, the two networks are on different domains, i keep having to use full name resolution i.e. ts.domain1.local and not just ts, using windows VPN i can just use ts. i have set up forward lookup zones on each dns server but it doesnt make any difference.

 i also have a problem when connecting to our main site's company web, get the "unauthorised ip". but if i connect locally using windows VPN, all of these issues go away so it has something to do with the 2 sonicwalls.

i have this error popping up every now and then:
24      05/18/2009 11:45:39.736      IKE Responder: IPSec proposal does not match (Phase 2)      91.84.16.74      82.152.225.206      192.168.49.0/24 -> 192.168.50.0/24       
25      05/18/2009 11:45:39.736      IKE Responder: No match for proposed remote network address      91.84.16.74      82.152.225.206      192.168.49.0/24

Which is odd as the remote networks are set on both sides to 192.168.50.0 and 192.168.102.0, so i dont know why its trying .49 ?

CONFUSED!!

Thanks for help in advance

Your first problem is one of DNS config I suspect. What DNS server is the remote user using to look up "ts"? If it isn't YOUR dns server then it won't find it. I suspect the remote user will be using his ISP's DNS server. But as you found you can use the FQDN, then, that's your solution - it's what FQDNs are for. :-)

The second one - you probably have the Proposal parameters incorrect but without seeing them we can't tell - please type in the following for EACH SITE

Wan address
Gateway address
LAN range

Settings from "General" tab of VPN config
Settings from networks tab
Settings from Proposals tab

There were some old Static routes setup on the Sonicwall that i didnt see before, so ive sorted out the VPN issues, DNS is still strange and cant access one server, only on though, will give you points for that though, cheers,
