Help with ACL for webserver behind cisco 857

[Tech.SJCM]

Hi Cisco community,

I'm looking for some help with configuring an ACL for a 857 Cisco router for web-server traffic.
I've configured a NAT for the inside network and added ACL entries for  port 80 access but dont seem to have any luck accessing the website  remotely.  I suspect there's an ACL rule blocking access.  Any help  would be greatly appreciated, thanks in advance.

Setup
Internet === Router === Webserver

Router address: 10.0.10.1
Web-server address: 10.0.10.77
IP from ISP address: XXX.XXX.XXX.XXX

(masked for security)

I changed the ACL to the following and had success accessing the website.
access-list 100 permit tcp any any eq 80

However I'd like to only allow access to the web-server 10.0.10.77

hi,

add these lines on your 857:

ip nat inside source static udp 10.0.10.77 53 XXX.XXX.XXX.XXX 53

no access-list 100 deny 53 any any

access-list 100 permit udp any host 10.0.10.77 eq 53
