question about VPN-IPSEC and NAT [7:30694]
Hello, I have in my organization a cisco router 2600 running NAT and IPSEC56. I want to configure two access-lists. One for inbound access and another one for outbound access and apply it in the same serial line. Does anyone know what are the ports I have to permit to work that job successfull as much inbound as outbound? I had success in configuring internet access and it4s working fine but over IPSEC my users from the other side of VPN can not access my exchange server using VPN. but they can ping it... thanks. Leonardo Borda.

IP protocol 50 and UDP port 500. If you are doing AH you also need ip protocol 51. -Eric -Original Message- From: Leonardo Borda [mailto:[EMAIL PROTECTED]] Sent: Wednesday, January 02, 2002 12:55 PM To: [EMAIL PROTECTED] Subject: question about VPN-IPSEC and NAT [7:30694] Hello, I have in my organization a cisco router 2600 running NAT and IPSEC56.

This is a remote access vpn situation? If you can ping the server then we can assume that the tunnel was set up correctly and it is not a situation where IPSec protocols are being blocked. Try playing with the IPSec over NAT setting on the client itself. >From: "Leonardo Borda" >Reply-To: "Leonardo Borda" >To: [EMAIL PROTECTED] >Subject: question about VPN-IPSEC and NAT [7:30694] >Date: Wed, 2 Jan 2002 13:55:14 -0500 > >Hello, > > I have in my organization a cisco router 2600 running NAT and IPSEC56. >I >want to configure two access-lists.
