Hello Everyone,  I have taken a /24 ip pool from IRINN (RIR) in India.

IRINN say they do RDNS only for full ip block and not for single IP. How can I get reverse DNS created and with whome... is there any publicly available service for it. Thanks Deepak Khemani ...

Hi All   We are planning any-connect VPN in tunnel mode for 80-100 concurrent users. Below are my questions   1. Which router we should look for 100 to 150 concurrent users? 2.Will it requires VPN acceleration card or it is inbuilt into router?  3.What type of licence will be required for any-connect VPN to support windows, Android and iPhone users? 4. We have a spare Cisco 2811 router. Will it support 100 users and will it require any licence or vpn card? 5. Also we want to test any-connect VPN. We have Cisco 1841 with 12.4 IOS. Is there any licence requirement for this? What I understand from blogs is that licence comes into picture if IOS is greater than 15.0 6. Does 12.4 IOS support Android and iPhone users?   Thanks in advance, Deepak Khemani     ... View more

  Hi All   I have a pool of public ip address 91.x.1x.0/28. I want to know if I can do static nat of server to last IP i.e. 91.x.1x.15.   I have a internet router connected to my ISP link and on other side is a appliance base firewall. I have configured a static route on router as   ip route 91.x.1x.0 255.255.255.20 <firewall IP address>   I am confused because in normal private IP addressing this will be a broadcast address.   Please reply and thanks in advance.     ...
