Actually we had some problem with our old router and today we replaced our router with Linksys model WAG200G.
Also we use ISA, for VPN clients we have to forward ports and I have forwarded the following ports also from this new router
50
500
51
1723
After this when VPN dial-up connection is trying to establish connection and it is only showing verifying user name and password.
It was working fine with our old router, is there any other things to be checked for VPnS in this router
Your earliest response is highly appreciated
