recently we had shifted our data center to a new place.
after this activity users are not able to connect to a remote server (public ip address) and it was working before shifitng the data center. it seems some connection went worng. the scenario of the data center is as follows:
cisco pix is having one public ip and one interface is connceted to cisco router and other end of pix is connected to lan switch. cisco router's 2nd interface is connected to mailmarshal server which has got one public ip. this connection is through a leased line. we have got another adsl line also where we have sonicwall x0 interface is connected to switch, x1 interface is connected to adsl router and x2 interface is connected to another adsl router.
cisco router has got one public ip
mailmarshal has got one public ip
cisco pix has got public ip
while shifting i think may be any connection went worng. there has been no change in any config for any devices made.
how can we resolve this
mainly users are not able to connect to remote server (public ip)
