Exclamation RPC: Remote system error - Permission denied

The people I used to work for who has been up and running for about 5 years and they have been running Fedora for about 6 months I upgraded them from older Redhat (7.1). Last month they changed ISPs. This shouldnít have been a big deal as all access is routed through a Cisco router running NAT on a few ports. The gateway is the Ethernet port of the Cisco router. The user has two other locations also routing through this Cisco (1720). The problems there are having is the two Linux servers (one running DHCPD, NIS and SMB the other is dialup services) canít connect anywhere with ssh, a web browser or ftp. Getting an error like this:

ssh: connect to host iron port 22: Permission denied

If I run rpcinfo I get:

rpcinfo: can't contact portmapper: RPC: Remote system error - Permission denied

I check the Cisco and the NAT config appears to be ok, and I can use ssh to get on these servers but once on I canít ssh elsewhere.

The ypwhich reports correctly for both machines and ypbind completed. But dhcpd isnít issuing IPís. Once I started DHCPD on the mid-range computer they have users PCís can connect to SMB shares and printers, get email (popped from off site) and use the web. I can even use the windows ssh to access either server. When I try and access anything from the server it fails. The user said they only changed the NAT translations and DNS servers in /etc/resolv.conf and /etc/dhcpd.conf.

I have been looking at this all day and hope a fresh set of eyes might see the obvious. I was called on Sunday the ISP change occurred last week. The user says everything was working except the ability to connect from the servers after the ISP change, but my monthly backups on Sunday morning reboots the two Linux servers so I wasnít able to confirm the problem before these other problems popped up.

Thanks for any help.

Best regards,
