What might be the difference in the roms that allow Wmodem use?

[wildpig]

I need some expert help from chefs and people with expertise in roms. I have flashed my TP2 with stock 6.1 and 6.5 ROM and in both instance, I couldn't get Wmodem to work.

I set up wmodem as the way I set it up in Mogul and TP1 and when I dial in, I am stucked on the verify username screen on the pc.

The only persons so far I know have Wmodem working on their TP2 is someone on Verizon and someone who said they got wmodem to work on their friend's sprint TP2 with some unknown custom 6.5.3 rom.

The verizon person said that for some reason when they have mightyrom and mr.x.rom, the start button in Wmodem is greyed out so they couldn't start the program. But when they flash back to Vzon stock 6.5 rom wmodem works with no problem at all and that it's actually included in the stock vzon rom (probably not with the tethering detection reg entries disabled)

The person that got it to work on their friends sprint TP2 doesn't know which rom it is.

The reason I really need Wmodem to work is that I need a non NATed ip. ICS while worked does not provide a non NAT ip to allow me to get thr IPSEC and nasty VPN at my workplace. I know that about 90% of the population here doesn't give a damn about Wmodem thinking that it's ancient but there are definitely advantages that ICS can't provide compared to Wmodem

I have a feeling that it's not EPST settings that is the problem because flashing different roms doesn't change EPST settings and I already compare EPST between my TP1 and TP2.

I really appreciate any help on this. I have spent about 6 hours everyday for the last 2 weeks chking various forums and posts trying to get Wmodem to work on my sprint TP2. BEside, I definitely think it's interesting to know exactly what it is that sprint did to really disable the use of wmodem. Thanks for any response..
