Thanks royalblues for your reply,,

but I have two cisco routers connected to the same firewall ,,I noticed that some TCP ports are not allowed on the second router so when my traffic directed to the second router only http services is allowed?????

That could depend on whether both devcies are running same code, are of same platform and have identical configurations.

One thing to note is that these services should not affect the traffic that is flowing through the router (unless u have some sort of access-lists) but only traffic directed to your router

no access-lists were applied to interfaces???is there any other config that my block some ports??
