had problem as i am not able to connect to dvr.i have forwarded port 80 for (web port)and another port 7777 in dvr for viewing dvr. intially when i assign dhcp by manually in dvr such as 192.168.1.115 my router doesn't show "in list of compuetr connected to router in router" dvr with this ip address, so i made it automatically in dvr then dvr took random ip address such as 192.168.1.102 which showed in router so i assign this ip(192.168.1.102) address manually to
dvr.my external ip address is 68.161.xxx.xxx(dynamic).when i tried to check port whether it is open or not with port checker software it showed me ,host unreacheable .i am using wrt54g2(cisco)
router.in this router i have range of assigning ip from 192.168.1.100-150. and connection status is dhcp
automatically.my management port is 8080.i am able see dvr from address such as 192.168.151.xxx in local network.but when i use my external ip+port in browser i am not able get conection.i have modem.router is atteached to modem.another when fed username and password of dyndns in router because i have dynamic ip address it took external ip address such as(192.168.251.100).which is not my external ip.
