E65 Ports?

[#1]

Does anyone happe to know all the ports i need to enable SIP on my E65?
If i use a 2091 router i have no problems though with the 1801HG i can surf the net but cannot register onto my VOIP service...
I have enabled all the standard ports such as:
UDP 5060
UDP 11113 
UDP 10300 - 10311
UDP 6901 - 6920
Is there something i am missing?
The reason i have asked is that i have seen a odd work around (using fring) though i want to use the built in SIP client. I have trawled through the Nokia developer forums though there are a number of people with the same issue......

I reckon it's a problem with the SIP client on the phone mate.
There are loads of posts across the net of people with SIP problems.
I can't even get the phone to perform automated periodic IMAP checks for my mailbox. Get so far into the setup and it just moans about a setting being enabled, which strictly is needed to do the function, but never the less is already disabled.
Use Fring. Much better anyway, seeing as it will integrate with Skype and MSN.

cheers i might give fring another go...
Saying that i have just carried out a firmware update on the router and it is now working though i will check again tomorrow as it worked before (on and off)...
With the 425.2 firmware i can alter the power rating to 400mw .... but i have set it to 100mw (uk limit)
