Cisco 2621 Router Configuration Limiting Inbound Connections
Posted on 2003-02-18
I have a Cisco 2621 router connected to a T1. I'm trying to achieve the following objectives and can't figure this out. The objectives are:
1. I want to allow incoming SMTP, POP3, WWW, Terminal Server, VNC, pcAnywhere and DNS. There is only one mail server with the same IP address and approximately 30 websites. The terminal server is only on one machine with VNC running on the web server. I have 3 DNS addresses. All these addresses are real-world IP addresses. The real world addresses use the subnet mask of 255.255.255.192 (64 IP's total).
2. Everything else inbound I want to block and log to an SNMP Server running on a 10.1.3.250 IP Address.
3. All internal computers are 10.1.3.1 to 10.1.3.255 with the gateway presently 10.1.3.1. I want all traffic allowed from the inbound to the outbound.
Thanks for your help, John
