cisco 3.5.1 over verizon dsl running winpoet

[s5umdj]

I have recently received a number of calls from my clients about problems running the cisco vpn desktop 3.5.1 to our cisco 3030 vpn concentrator. Clients running Netscape mail are complaining about not being able to send mail with large attachments. Whenever they try they are kicked off of the network. Is anyone aware of any problems with verizon dsl or winpoet?

Hi,

you can try lowering down the MTU on the client machines to around 1200B, and also try using the "Clear DF" bit option for private interface.

Thanks,

Afaq
