Hi all,
I have two ISP links one with a fix Ip address and I want to use them in a cisco 1900 router in load sharing and allow to my partner to acces to our server with FTP and use the IP fix.
the problem is that i already used NAt but it seems that there is something messing in my configuration cause the server obtiens the non fixed IP address so our clients can't access to our server and if I use just the link with adsl IP fix it's working fine: can some one please help me to clear this probleme.
my configuration is as follow:

thanks in advance.

first of all you dont need udp 21
but you need tcp 20 too
ip nat inside source static tcp 192.168.2.200 21 interface Dialer0 21
no ip nat inside source static udp 192.168.2.200 21 interface Dialer0 21
ip nat inside source static tcp 192.168.2.200 20 interface Dialer0 20
not concernig two nat
